Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508272, here are decompositions:
- 41 + 31508231 = 31508272
- 101 + 31508171 = 31508272
- 113 + 31508159 = 31508272
- 179 + 31508093 = 31508272
- 233 + 31508039 = 31508272
- 269 + 31508003 = 31508272
- 281 + 31507991 = 31508272
- 359 + 31507913 = 31508272
Showing the first eight; more decompositions exist.
