Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512100, here are decompositions:
- 7 + 512093 = 512100
- 41 + 512059 = 512100
- 53 + 512047 = 512100
- 79 + 512021 = 512100
- 89 + 512011 = 512100
- 103 + 511997 = 512100
- 109 + 511991 = 512100
- 137 + 511963 = 512100
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 512,100 and was likely granted around 1893.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 512100 first appears in π at position 634,112 of the decimal expansion (the 634,112ordinal-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.
