Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522, here are decompositions:
- 5 + 31517 = 31522
- 11 + 31511 = 31522
- 41 + 31481 = 31522
- 53 + 31469 = 31522
- 131 + 31391 = 31522
- 251 + 31271 = 31522
- 263 + 31259 = 31522
- 269 + 31253 = 31522
Showing the first eight; more decompositions exist.
