Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541992, here are decompositions:
- 3 + 31541989 = 31541992
- 11 + 31541981 = 31541992
- 59 + 31541933 = 31541992
- 89 + 31541903 = 31541992
- 101 + 31541891 = 31541992
- 359 + 31541633 = 31541992
- 401 + 31541591 = 31541992
- 509 + 31541483 = 31541992
Showing the first eight; more decompositions exist.
