Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118642, here are decompositions:
- 23 + 118619 = 118642
- 53 + 118589 = 118642
- 59 + 118583 = 118642
- 71 + 118571 = 118642
- 113 + 118529 = 118642
- 149 + 118493 = 118642
- 179 + 118463 = 118642
- 233 + 118409 = 118642
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 118,642 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 118642 first appears in π at position 975,329 of the decimal expansion (the 975,329ordinal-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.
