Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512406, here are decompositions:
- 17 + 512389 = 512406
- 53 + 512353 = 512406
- 73 + 512333 = 512406
- 137 + 512269 = 512406
- 157 + 512249 = 512406
- 199 + 512207 = 512406
- 239 + 512167 = 512406
- 269 + 512137 = 512406
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 512,406 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 512406 first appears in π at position 771,088 of the decimal expansion (the 771,088ordinal-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.
