Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31270, here are decompositions:
- 3 + 31267 = 31270
- 11 + 31259 = 31270
- 17 + 31253 = 31270
- 23 + 31247 = 31270
- 47 + 31223 = 31270
- 89 + 31181 = 31270
- 131 + 31139 = 31270
- 149 + 31121 = 31270
Showing the first eight; more decompositions exist.
