Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564992, here are decompositions:
- 13 + 31564979 = 31564992
- 59 + 31564933 = 31564992
- 71 + 31564921 = 31564992
- 73 + 31564919 = 31564992
- 101 + 31564891 = 31564992
- 113 + 31564879 = 31564992
- 139 + 31564853 = 31564992
- 211 + 31564781 = 31564992
Showing the first eight; more decompositions exist.
