Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545702, here are decompositions:
- 61 + 31545641 = 31545702
- 73 + 31545629 = 31545702
- 79 + 31545623 = 31545702
- 103 + 31545599 = 31545702
- 233 + 31545469 = 31545702
- 263 + 31545439 = 31545702
- 311 + 31545391 = 31545702
- 359 + 31545343 = 31545702
Showing the first eight; more decompositions exist.
