Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459928, here are decompositions:
- 37 + 31459891 = 31459928
- 79 + 31459849 = 31459928
- 211 + 31459717 = 31459928
- 277 + 31459651 = 31459928
- 307 + 31459621 = 31459928
- 541 + 31459387 = 31459928
- 571 + 31459357 = 31459928
- 607 + 31459321 = 31459928
Showing the first eight; more decompositions exist.
