Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31360, here are decompositions:
- 3 + 31357 = 31360
- 23 + 31337 = 31360
- 41 + 31319 = 31360
- 53 + 31307 = 31360
- 83 + 31277 = 31360
- 89 + 31271 = 31360
- 101 + 31259 = 31360
- 107 + 31253 = 31360
Showing the first eight; more decompositions exist.
