Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552526, here are decompositions:
- 37 + 31552489 = 31552526
- 97 + 31552429 = 31552526
- 139 + 31552387 = 31552526
- 223 + 31552303 = 31552526
- 457 + 31552069 = 31552526
- 547 + 31551979 = 31552526
- 673 + 31551853 = 31552526
- 769 + 31551757 = 31552526
Showing the first eight; more decompositions exist.
