Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42474, here are decompositions:
- 7 + 42467 = 42474
- 11 + 42463 = 42474
- 13 + 42461 = 42474
- 17 + 42457 = 42474
- 23 + 42451 = 42474
- 31 + 42443 = 42474
- 37 + 42437 = 42474
- 41 + 42433 = 42474
Showing the first eight; more decompositions exist.
