Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105070, here are decompositions:
- 47 + 105023 = 105070
- 71 + 104999 = 105070
- 83 + 104987 = 105070
- 137 + 104933 = 105070
- 179 + 104891 = 105070
- 191 + 104879 = 105070
- 239 + 104831 = 105070
- 269 + 104801 = 105070
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 105,070 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 105070 first appears in π at position 9,675 of the decimal expansion (the 9,675ordinal-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.
