Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459916, here are decompositions:
- 67 + 31459849 = 31459916
- 109 + 31459807 = 31459916
- 157 + 31459759 = 31459916
- 193 + 31459723 = 31459916
- 199 + 31459717 = 31459916
- 283 + 31459633 = 31459916
- 307 + 31459609 = 31459916
- 577 + 31459339 = 31459916
Showing the first eight; more decompositions exist.
