Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459632, here are decompositions:
- 11 + 31459621 = 31459632
- 13 + 31459619 = 31459632
- 23 + 31459609 = 31459632
- 79 + 31459553 = 31459632
- 199 + 31459433 = 31459632
- 223 + 31459409 = 31459632
- 233 + 31459399 = 31459632
- 283 + 31459349 = 31459632
Showing the first eight; more decompositions exist.
