Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528424, here are decompositions:
- 61 + 31528363 = 31528424
- 97 + 31528327 = 31528424
- 157 + 31528267 = 31528424
- 211 + 31528213 = 31528424
- 313 + 31528111 = 31528424
- 331 + 31528093 = 31528424
- 457 + 31527967 = 31528424
- 607 + 31527817 = 31528424
Showing the first eight; more decompositions exist.
