Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545988, here are decompositions:
- 29 + 31545959 = 31545988
- 101 + 31545887 = 31545988
- 239 + 31545749 = 31545988
- 251 + 31545737 = 31545988
- 347 + 31545641 = 31545988
- 359 + 31545629 = 31545988
- 389 + 31545599 = 31545988
- 587 + 31545401 = 31545988
Showing the first eight; more decompositions exist.
