Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528912, here are decompositions:
- 3 + 31528909 = 31528912
- 59 + 31528853 = 31528912
- 71 + 31528841 = 31528912
- 89 + 31528823 = 31528912
- 101 + 31528811 = 31528912
- 353 + 31528559 = 31528912
- 461 + 31528451 = 31528912
- 479 + 31528433 = 31528912
Showing the first eight; more decompositions exist.
