Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545678, here are decompositions:
- 11 + 31545667 = 31545678
- 37 + 31545641 = 31545678
- 67 + 31545611 = 31545678
- 71 + 31545607 = 31545678
- 79 + 31545599 = 31545678
- 179 + 31545499 = 31545678
- 191 + 31545487 = 31545678
- 239 + 31545439 = 31545678
Showing the first eight; more decompositions exist.
