Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497944, here are decompositions:
- 3 + 31497941 = 31497944
- 13 + 31497931 = 31497944
- 61 + 31497883 = 31497944
- 73 + 31497871 = 31497944
- 193 + 31497751 = 31497944
- 223 + 31497721 = 31497944
- 271 + 31497673 = 31497944
- 277 + 31497667 = 31497944
Showing the first eight; more decompositions exist.
