Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497722, here are decompositions:
- 43 + 31497679 = 31497722
- 163 + 31497559 = 31497722
- 181 + 31497541 = 31497722
- 199 + 31497523 = 31497722
- 313 + 31497409 = 31497722
- 331 + 31497391 = 31497722
- 409 + 31497313 = 31497722
- 439 + 31497283 = 31497722
Showing the first eight; more decompositions exist.
