Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542468, here are decompositions:
- 11 + 31542457 = 31542468
- 29 + 31542439 = 31542468
- 31 + 31542437 = 31542468
- 71 + 31542397 = 31542468
- 109 + 31542359 = 31542468
- 127 + 31542341 = 31542468
- 239 + 31542229 = 31542468
- 271 + 31542197 = 31542468
Showing the first eight; more decompositions exist.
