Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42552, here are decompositions:
- 19 + 42533 = 42552
- 43 + 42509 = 42552
- 53 + 42499 = 42552
- 61 + 42491 = 42552
- 79 + 42473 = 42552
- 89 + 42463 = 42552
- 101 + 42451 = 42552
- 109 + 42443 = 42552
Showing the first eight; more decompositions exist.
