Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528446, here are decompositions:
- 13 + 31528433 = 31528446
- 73 + 31528373 = 31528446
- 83 + 31528363 = 31528446
- 97 + 31528349 = 31528446
- 109 + 31528337 = 31528446
- 163 + 31528283 = 31528446
- 167 + 31528279 = 31528446
- 179 + 31528267 = 31528446
Showing the first eight; more decompositions exist.
