Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534500, here are decompositions:
- 7 + 31534493 = 31534500
- 13 + 31534487 = 31534500
- 17 + 31534483 = 31534500
- 43 + 31534457 = 31534500
- 59 + 31534441 = 31534500
- 71 + 31534429 = 31534500
- 73 + 31534427 = 31534500
- 89 + 31534411 = 31534500
Showing the first eight; more decompositions exist.
