Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978458, here are decompositions:

  • 31 + 978427 = 978458
  • 109 + 978349 = 978458
  • 181 + 978277 = 978458
  • 241 + 978217 = 978458
  • 277 + 978181 = 978458
  • 307 + 978151 = 978458
  • 367 + 978091 = 978458
  • 379 + 978079 = 978458

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 978,458 and was likely granted around 1910.

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

Position in π

The digit sequence 978458 first appears in π at position 380,588 of the decimal expansion (the 380,588ordinal-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.
