Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625630, here are decompositions:
- 13 + 31625617 = 31625630
- 31 + 31625599 = 31625630
- 67 + 31625563 = 31625630
- 163 + 31625467 = 31625630
- 199 + 31625431 = 31625630
- 229 + 31625401 = 31625630
- 349 + 31625281 = 31625630
- 367 + 31625263 = 31625630
Showing the first eight; more decompositions exist.
