Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31308, here are decompositions:
- 31 + 31277 = 31308
- 37 + 31271 = 31308
- 41 + 31267 = 31308
- 59 + 31249 = 31308
- 61 + 31247 = 31308
- 71 + 31237 = 31308
- 89 + 31219 = 31308
- 127 + 31181 = 31308
Showing the first eight; more decompositions exist.
