Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528370, here are decompositions:
- 7 + 31528363 = 31528370
- 43 + 31528327 = 31528370
- 79 + 31528291 = 31528370
- 103 + 31528267 = 31528370
- 157 + 31528213 = 31528370
- 163 + 31528207 = 31528370
- 199 + 31528171 = 31528370
- 277 + 31528093 = 31528370
Showing the first eight; more decompositions exist.
