Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627344, here are decompositions:
- 11 + 31627333 = 31627344
- 41 + 31627303 = 31627344
- 83 + 31627261 = 31627344
- 97 + 31627247 = 31627344
- 101 + 31627243 = 31627344
- 107 + 31627237 = 31627344
- 127 + 31627217 = 31627344
- 193 + 31627151 = 31627344
Showing the first eight; more decompositions exist.
