Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79620, here are decompositions:
- 7 + 79613 = 79620
- 11 + 79609 = 79620
- 19 + 79601 = 79620
- 31 + 79589 = 79620
- 41 + 79579 = 79620
- 59 + 79561 = 79620
- 61 + 79559 = 79620
- 71 + 79549 = 79620
Showing the first eight; more decompositions exist.
