Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528410, here are decompositions:
- 37 + 31528373 = 31528410
- 47 + 31528363 = 31528410
- 61 + 31528349 = 31528410
- 73 + 31528337 = 31528410
- 83 + 31528327 = 31528410
- 97 + 31528313 = 31528410
- 127 + 31528283 = 31528410
- 131 + 31528279 = 31528410
Showing the first eight; more decompositions exist.
