Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78442, here are decompositions:
- 3 + 78439 = 78442
- 5 + 78437 = 78442
- 41 + 78401 = 78442
- 101 + 78341 = 78442
- 131 + 78311 = 78442
- 239 + 78203 = 78442
- 251 + 78191 = 78442
- 263 + 78179 = 78442
Showing the first eight; more decompositions exist.
