Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542824, here are decompositions:
- 13 + 31542811 = 31542824
- 37 + 31542787 = 31542824
- 97 + 31542727 = 31542824
- 127 + 31542697 = 31542824
- 193 + 31542631 = 31542824
- 211 + 31542613 = 31542824
- 277 + 31542547 = 31542824
- 337 + 31542487 = 31542824
Showing the first eight; more decompositions exist.
