Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545684, here are decompositions:
- 17 + 31545667 = 31545684
- 43 + 31545641 = 31545684
- 61 + 31545623 = 31545684
- 73 + 31545611 = 31545684
- 197 + 31545487 = 31545684
- 277 + 31545407 = 31545684
- 283 + 31545401 = 31545684
- 293 + 31545391 = 31545684
Showing the first eight; more decompositions exist.
