Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31282, here are decompositions:
- 5 + 31277 = 31282
- 11 + 31271 = 31282
- 23 + 31259 = 31282
- 29 + 31253 = 31282
- 59 + 31223 = 31282
- 89 + 31193 = 31282
- 101 + 31181 = 31282
- 131 + 31151 = 31282
Showing the first eight; more decompositions exist.
