Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142502, here are decompositions:
- 271 + 142231 = 142502
- 313 + 142189 = 142502
- 379 + 142123 = 142502
- 463 + 142039 = 142502
- 541 + 141961 = 142502
- 571 + 141931 = 142502
- 631 + 141871 = 142502
- 673 + 141829 = 142502
Showing the first eight; more decompositions exist.
