Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455962, here are decompositions:
- 3 + 31455959 = 31455962
- 61 + 31455901 = 31455962
- 73 + 31455889 = 31455962
- 103 + 31455859 = 31455962
- 211 + 31455751 = 31455962
- 313 + 31455649 = 31455962
- 331 + 31455631 = 31455962
- 463 + 31455499 = 31455962
Showing the first eight; more decompositions exist.
