Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666942, here are decompositions:
- 3 + 8666939 = 8666942
- 61 + 8666881 = 8666942
- 79 + 8666863 = 8666942
- 103 + 8666839 = 8666942
- 409 + 8666533 = 8666942
- 463 + 8666479 = 8666942
- 499 + 8666443 = 8666942
- 523 + 8666419 = 8666942
Showing the first eight; more decompositions exist.
