Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189856, here are decompositions:

  • 3 + 189853 = 189856
  • 5 + 189851 = 189856
  • 59 + 189797 = 189856
  • 89 + 189767 = 189856
  • 113 + 189743 = 189856
  • 239 + 189617 = 189856
  • 257 + 189599 = 189856
  • 263 + 189593 = 189856

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 189,856 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 189856 first appears in π at position 940,076 of the decimal expansion (the 940,076ordinal-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.
