Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 113428, here are decompositions:
- 11 + 113417 = 113428
- 47 + 113381 = 113428
- 71 + 113357 = 113428
- 101 + 113327 = 113428
- 149 + 113279 = 113428
- 239 + 113189 = 113428
- 251 + 113177 = 113428
- 257 + 113171 = 113428
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 113,428 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 113428 first appears in π at position 265,637 of the decimal expansion (the 265,637ordinal-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.
