Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23986, here are decompositions:
- 5 + 23981 = 23986
- 29 + 23957 = 23986
- 107 + 23879 = 23986
- 113 + 23873 = 23986
- 167 + 23819 = 23986
- 173 + 23813 = 23986
- 197 + 23789 = 23986
- 233 + 23753 = 23986
Showing the first eight; more decompositions exist.

The digit sequence 23986 first appears in π at position 2,447 of the decimal expansion (the 2,447ordinal-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.
