Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531232, here are decompositions:
- 163 + 31531069 = 31531232
- 331 + 31530901 = 31531232
- 433 + 31530799 = 31531232
- 571 + 31530661 = 31531232
- 643 + 31530589 = 31531232
- 661 + 31530571 = 31531232
- 709 + 31530523 = 31531232
- 823 + 31530409 = 31531232
Showing the first eight; more decompositions exist.
