Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742846, here are decompositions:
- 29 + 8742817 = 8742846
- 59 + 8742787 = 8742846
- 67 + 8742779 = 8742846
- 107 + 8742739 = 8742846
- 157 + 8742689 = 8742846
- 173 + 8742673 = 8742846
- 193 + 8742653 = 8742846
- 223 + 8742623 = 8742846
Showing the first eight; more decompositions exist.
