Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531070, here are decompositions:
- 7 + 31531063 = 31531070
- 13 + 31531057 = 31531070
- 97 + 31530973 = 31531070
- 127 + 31530943 = 31531070
- 229 + 31530841 = 31531070
- 271 + 31530799 = 31531070
- 367 + 31530703 = 31531070
- 409 + 31530661 = 31531070
Showing the first eight; more decompositions exist.
