Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459792, here are decompositions:
- 59 + 31459733 = 31459792
- 83 + 31459709 = 31459792
- 113 + 31459679 = 31459792
- 131 + 31459661 = 31459792
- 173 + 31459619 = 31459792
- 239 + 31459553 = 31459792
- 251 + 31459541 = 31459792
- 293 + 31459499 = 31459792
Showing the first eight; more decompositions exist.
