Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463428, here are decompositions:
- 41 + 31463387 = 31463428
- 107 + 31463321 = 31463428
- 167 + 31463261 = 31463428
- 179 + 31463249 = 31463428
- 281 + 31463147 = 31463428
- 449 + 31462979 = 31463428
- 617 + 31462811 = 31463428
- 677 + 31462751 = 31463428
Showing the first eight; more decompositions exist.
