Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7512, here are decompositions:
- 5 + 7507 = 7512
- 13 + 7499 = 7512
- 23 + 7489 = 7512
- 31 + 7481 = 7512
- 53 + 7459 = 7512
- 61 + 7451 = 7512
- 79 + 7433 = 7512
- 101 + 7411 = 7512
Showing the first eight; more decompositions exist.
