Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593960, here are decompositions:
- 7 + 31593953 = 31593960
- 17 + 31593943 = 31593960
- 23 + 31593937 = 31593960
- 29 + 31593931 = 31593960
- 59 + 31593901 = 31593960
- 127 + 31593833 = 31593960
- 163 + 31593797 = 31593960
- 173 + 31593787 = 31593960
Showing the first eight; more decompositions exist.
