Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459984, here are decompositions:
- 47 + 31459937 = 31459984
- 53 + 31459931 = 31459984
- 131 + 31459853 = 31459984
- 137 + 31459847 = 31459984
- 251 + 31459733 = 31459984
- 317 + 31459667 = 31459984
- 431 + 31459553 = 31459984
- 443 + 31459541 = 31459984
Showing the first eight; more decompositions exist.
