Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513694, here are decompositions:
- 73 + 31513621 = 31513694
- 271 + 31513423 = 31513694
- 283 + 31513411 = 31513694
- 547 + 31513147 = 31513694
- 571 + 31513123 = 31513694
- 577 + 31513117 = 31513694
- 631 + 31513063 = 31513694
- 661 + 31513033 = 31513694
Showing the first eight; more decompositions exist.
