Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534490, here are decompositions:
- 3 + 31534487 = 31534490
- 7 + 31534483 = 31534490
- 61 + 31534429 = 31534490
- 67 + 31534423 = 31534490
- 79 + 31534411 = 31534490
- 157 + 31534333 = 31534490
- 193 + 31534297 = 31534490
- 307 + 31534183 = 31534490
Showing the first eight; more decompositions exist.
