Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579750, here are decompositions:
- 3 + 31579747 = 31579750
- 11 + 31579739 = 31579750
- 29 + 31579721 = 31579750
- 47 + 31579703 = 31579750
- 89 + 31579661 = 31579750
- 107 + 31579643 = 31579750
- 131 + 31579619 = 31579750
- 239 + 31579511 = 31579750
Showing the first eight; more decompositions exist.
