Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 113730, here are decompositions:
- 7 + 113723 = 113730
- 11 + 113719 = 113730
- 13 + 113717 = 113730
- 47 + 113683 = 113730
- 73 + 113657 = 113730
- 83 + 113647 = 113730
- 107 + 113623 = 113730
- 109 + 113621 = 113730
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 113,730 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 113730 first appears in π at position 445,349 of the decimal expansion (the 445,349ordinal-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.
