Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629842, here are decompositions:
- 19 + 8629823 = 8629842
- 29 + 8629813 = 8629842
- 71 + 8629771 = 8629842
- 79 + 8629763 = 8629842
- 103 + 8629739 = 8629842
- 131 + 8629711 = 8629842
- 163 + 8629679 = 8629842
- 181 + 8629661 = 8629842
Showing the first eight; more decompositions exist.
