Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506660, here are decompositions:
- 13 + 506647 = 506660
- 31 + 506629 = 506660
- 61 + 506599 = 506660
- 67 + 506593 = 506660
- 97 + 506563 = 506660
- 109 + 506551 = 506660
- 127 + 506533 = 506660
- 181 + 506479 = 506660
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 506,660 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 506660 first appears in π at position 149,749 of the decimal expansion (the 149,749ordinal-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.
