Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79440, here are decompositions:
- 7 + 79433 = 79440
- 13 + 79427 = 79440
- 17 + 79423 = 79440
- 29 + 79411 = 79440
- 41 + 79399 = 79440
- 43 + 79397 = 79440
- 47 + 79393 = 79440
- 61 + 79379 = 79440
Showing the first eight; more decompositions exist.
