Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455016, here are decompositions:
- 17 + 31454999 = 31455016
- 59 + 31454957 = 31455016
- 107 + 31454909 = 31455016
- 113 + 31454903 = 31455016
- 149 + 31454867 = 31455016
- 179 + 31454837 = 31455016
- 233 + 31454783 = 31455016
- 347 + 31454669 = 31455016
Showing the first eight; more decompositions exist.
