Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31310, here are decompositions:
- 3 + 31307 = 31310
- 43 + 31267 = 31310
- 61 + 31249 = 31310
- 73 + 31237 = 31310
- 79 + 31231 = 31310
- 127 + 31183 = 31310
- 151 + 31159 = 31310
- 157 + 31153 = 31310
Showing the first eight; more decompositions exist.
