Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539348, here are decompositions:
- 11 + 31539337 = 31539348
- 17 + 31539331 = 31539348
- 19 + 31539329 = 31539348
- 59 + 31539289 = 31539348
- 107 + 31539241 = 31539348
- 157 + 31539191 = 31539348
- 397 + 31538951 = 31539348
- 461 + 31538887 = 31539348
Showing the first eight; more decompositions exist.
