Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566600, here are decompositions:
- 11 + 31566589 = 31566600
- 41 + 31566559 = 31566600
- 53 + 31566547 = 31566600
- 59 + 31566541 = 31566600
- 73 + 31566527 = 31566600
- 83 + 31566517 = 31566600
- 103 + 31566497 = 31566600
- 113 + 31566487 = 31566600
Showing the first eight; more decompositions exist.
