Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534512, here are decompositions:
- 11 + 31534501 = 31534512
- 19 + 31534493 = 31534512
- 29 + 31534483 = 31534512
- 71 + 31534441 = 31534512
- 83 + 31534429 = 31534512
- 89 + 31534423 = 31534512
- 101 + 31534411 = 31534512
- 179 + 31534333 = 31534512
Showing the first eight; more decompositions exist.
