Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79040, here are decompositions:
- 61 + 78979 = 79040
- 139 + 78901 = 79040
- 151 + 78889 = 79040
- 163 + 78877 = 79040
- 349 + 78691 = 79040
- 397 + 78643 = 79040
- 433 + 78607 = 79040
- 457 + 78583 = 79040
Showing the first eight; more decompositions exist.
