Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942720, here are decompositions:
- 11 + 942709 = 942720
- 29 + 942691 = 942720
- 59 + 942661 = 942720
- 61 + 942659 = 942720
- 67 + 942653 = 942720
- 83 + 942637 = 942720
- 113 + 942607 = 942720
- 127 + 942593 = 942720
Showing the first eight; more decompositions exist.
