Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42516, here are decompositions:
- 7 + 42509 = 42516
- 17 + 42499 = 42516
- 29 + 42487 = 42516
- 43 + 42473 = 42516
- 53 + 42463 = 42516
- 59 + 42457 = 42516
- 73 + 42443 = 42516
- 79 + 42437 = 42516
Showing the first eight; more decompositions exist.
