Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497908, here are decompositions:
- 37 + 31497871 = 31497908
- 151 + 31497757 = 31497908
- 157 + 31497751 = 31497908
- 181 + 31497727 = 31497908
- 229 + 31497679 = 31497908
- 241 + 31497667 = 31497908
- 271 + 31497637 = 31497908
- 307 + 31497601 = 31497908
Showing the first eight; more decompositions exist.
