Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9868, here are decompositions:
- 11 + 9857 = 9868
- 17 + 9851 = 9868
- 29 + 9839 = 9868
- 101 + 9767 = 9868
- 149 + 9719 = 9868
- 179 + 9689 = 9868
- 191 + 9677 = 9868
- 239 + 9629 = 9868
Showing the first eight; more decompositions exist.

The digit sequence 9868 first appears in π at position 7,042 of the decimal expansion (the 7,042ordinal-suffix:nd 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.
