Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542764, here are decompositions:
- 37 + 31542727 = 31542764
- 61 + 31542703 = 31542764
- 67 + 31542697 = 31542764
- 151 + 31542613 = 31542764
- 241 + 31542523 = 31542764
- 277 + 31542487 = 31542764
- 307 + 31542457 = 31542764
- 367 + 31542397 = 31542764
Showing the first eight; more decompositions exist.
