Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472928, here are decompositions:
- 37 + 31472891 = 31472928
- 41 + 31472887 = 31472928
- 61 + 31472867 = 31472928
- 79 + 31472849 = 31472928
- 89 + 31472839 = 31472928
- 101 + 31472827 = 31472928
- 229 + 31472699 = 31472928
- 317 + 31472611 = 31472928
Showing the first eight; more decompositions exist.
