Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509526, here are decompositions:
- 3 + 31509523 = 31509526
- 107 + 31509419 = 31509526
- 197 + 31509329 = 31509526
- 353 + 31509173 = 31509526
- 449 + 31509077 = 31509526
- 509 + 31509017 = 31509526
- 683 + 31508843 = 31509526
- 887 + 31508639 = 31509526
Showing the first eight; more decompositions exist.
