Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528952, here are decompositions:
- 43 + 31528909 = 31528952
- 109 + 31528843 = 31528952
- 139 + 31528813 = 31528952
- 151 + 31528801 = 31528952
- 211 + 31528741 = 31528952
- 223 + 31528729 = 31528952
- 229 + 31528723 = 31528952
- 283 + 31528669 = 31528952
Showing the first eight; more decompositions exist.
