Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542408, here are decompositions:
- 11 + 31542397 = 31542408
- 17 + 31542391 = 31542408
- 31 + 31542377 = 31542408
- 67 + 31542341 = 31542408
- 127 + 31542281 = 31542408
- 179 + 31542229 = 31542408
- 211 + 31542197 = 31542408
- 397 + 31542011 = 31542408
Showing the first eight; more decompositions exist.
