Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502, here are decompositions:
- 3 + 499 = 502
- 11 + 491 = 502
- 23 + 479 = 502
- 41 + 461 = 502
- 53 + 449 = 502
- 59 + 443 = 502
- 71 + 431 = 502
- 83 + 419 = 502
Showing the first eight; more decompositions exist.
