Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612, here are decompositions:
- 5 + 31607 = 31612
- 11 + 31601 = 31612
- 29 + 31583 = 31612
- 71 + 31541 = 31612
- 101 + 31511 = 31612
- 131 + 31481 = 31612
- 233 + 31379 = 31612
- 293 + 31319 = 31612
Showing the first eight; more decompositions exist.
