Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178298, here are decompositions:

  • 37 + 178261 = 178298
  • 67 + 178231 = 178298
  • 157 + 178141 = 178298
  • 181 + 178117 = 178298
  • 229 + 178069 = 178298
  • 277 + 178021 = 178298
  • 331 + 177967 = 178298
  • 349 + 177949 = 178298

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 178,298 and was likely granted around 1875.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 178298 first appears in π at position 578,247 of the decimal expansion (the 578,247ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
