Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472216, here are decompositions:
- 7 + 31472209 = 31472216
- 37 + 31472179 = 31472216
- 67 + 31472149 = 31472216
- 73 + 31472143 = 31472216
- 109 + 31472107 = 31472216
- 163 + 31472053 = 31472216
- 277 + 31471939 = 31472216
- 283 + 31471933 = 31472216
Showing the first eight; more decompositions exist.
