Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461904, here are decompositions:
- 11 + 31461893 = 31461904
- 17 + 31461887 = 31461904
- 53 + 31461851 = 31461904
- 113 + 31461791 = 31461904
- 167 + 31461737 = 31461904
- 251 + 31461653 = 31461904
- 263 + 31461641 = 31461904
- 347 + 31461557 = 31461904
Showing the first eight; more decompositions exist.
