Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42480, here are decompositions:
- 7 + 42473 = 42480
- 13 + 42467 = 42480
- 17 + 42463 = 42480
- 19 + 42461 = 42480
- 23 + 42457 = 42480
- 29 + 42451 = 42480
- 37 + 42443 = 42480
- 43 + 42437 = 42480
Showing the first eight; more decompositions exist.
