Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42502, here are decompositions:
- 3 + 42499 = 42502
- 11 + 42491 = 42502
- 29 + 42473 = 42502
- 41 + 42461 = 42502
- 59 + 42443 = 42502
- 179 + 42323 = 42502
- 263 + 42239 = 42502
- 281 + 42221 = 42502
Showing the first eight; more decompositions exist.
