Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625624, here are decompositions:
- 7 + 31625617 = 31625624
- 61 + 31625563 = 31625624
- 157 + 31625467 = 31625624
- 193 + 31625431 = 31625624
- 223 + 31625401 = 31625624
- 241 + 31625383 = 31625624
- 673 + 31624951 = 31625624
- 787 + 31624837 = 31625624
Showing the first eight; more decompositions exist.
