Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552, here are decompositions:
- 5 + 31547 = 31552
- 11 + 31541 = 31552
- 41 + 31511 = 31552
- 71 + 31481 = 31552
- 83 + 31469 = 31552
- 173 + 31379 = 31552
- 233 + 31319 = 31552
- 281 + 31271 = 31552
Showing the first eight; more decompositions exist.
