Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79642, here are decompositions:
- 11 + 79631 = 79642
- 29 + 79613 = 79642
- 41 + 79601 = 79642
- 53 + 79589 = 79642
- 83 + 79559 = 79642
- 149 + 79493 = 79642
- 191 + 79451 = 79642
- 263 + 79379 = 79642
Showing the first eight; more decompositions exist.
