Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86280, here are decompositions:
- 11 + 86269 = 86280
- 17 + 86263 = 86280
- 23 + 86257 = 86280
- 31 + 86249 = 86280
- 37 + 86243 = 86280
- 41 + 86239 = 86280
- 71 + 86209 = 86280
- 79 + 86201 = 86280
Showing the first eight; more decompositions exist.

The digit sequence 86280 first appears in π at position 81 of the decimal expansion (the 81ordinal-suffix:st 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.
