Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528870, here are decompositions:
- 17 + 31528853 = 31528870
- 29 + 31528841 = 31528870
- 47 + 31528823 = 31528870
- 59 + 31528811 = 31528870
- 173 + 31528697 = 31528870
- 257 + 31528613 = 31528870
- 311 + 31528559 = 31528870
- 419 + 31528451 = 31528870
Showing the first eight; more decompositions exist.
