Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590960, here are decompositions:
- 17 + 31590943 = 31590960
- 19 + 31590941 = 31590960
- 29 + 31590931 = 31590960
- 31 + 31590929 = 31590960
- 43 + 31590917 = 31590960
- 53 + 31590907 = 31590960
- 61 + 31590899 = 31590960
- 67 + 31590893 = 31590960
Showing the first eight; more decompositions exist.
