Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528094, here are decompositions:
- 97 + 31527997 = 31528094
- 127 + 31527967 = 31528094
- 163 + 31527931 = 31528094
- 181 + 31527913 = 31528094
- 277 + 31527817 = 31528094
- 307 + 31527787 = 31528094
- 313 + 31527781 = 31528094
- 397 + 31527697 = 31528094
Showing the first eight; more decompositions exist.
