Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530158, here are decompositions:
- 61 + 31530097 = 31530158
- 97 + 31530061 = 31530158
- 157 + 31530001 = 31530158
- 181 + 31529977 = 31530158
- 277 + 31529881 = 31530158
- 409 + 31529749 = 31530158
- 487 + 31529671 = 31530158
- 601 + 31529557 = 31530158
Showing the first eight; more decompositions exist.
