Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553624, here are decompositions:
- 7 + 31553617 = 31553624
- 97 + 31553527 = 31553624
- 241 + 31553383 = 31553624
- 463 + 31553161 = 31553624
- 547 + 31553077 = 31553624
- 607 + 31553017 = 31553624
- 733 + 31552891 = 31553624
- 877 + 31552747 = 31553624
Showing the first eight; more decompositions exist.
