Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529128, here are decompositions:
- 41 + 31529087 = 31529128
- 47 + 31529081 = 31529128
- 131 + 31528997 = 31529128
- 317 + 31528811 = 31529128
- 431 + 31528697 = 31529128
- 569 + 31528559 = 31529128
- 677 + 31528451 = 31529128
- 887 + 31528241 = 31529128
Showing the first eight; more decompositions exist.
