Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459790, here are decompositions:
- 31 + 31459759 = 31459790
- 67 + 31459723 = 31459790
- 73 + 31459717 = 31459790
- 139 + 31459651 = 31459790
- 157 + 31459633 = 31459790
- 181 + 31459609 = 31459790
- 433 + 31459357 = 31459790
- 499 + 31459291 = 31459790
Showing the first eight; more decompositions exist.
