Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100430, here are decompositions:
- 13 + 100417 = 100430
- 19 + 100411 = 100430
- 37 + 100393 = 100430
- 67 + 100363 = 100430
- 73 + 100357 = 100430
- 97 + 100333 = 100430
- 139 + 100291 = 100430
- 151 + 100279 = 100430
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 100,430 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 100430 first appears in π at position 40,079 of the decimal expansion (the 40,079ordinal-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.
