Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78444, here are decompositions:
- 5 + 78439 = 78444
- 7 + 78437 = 78444
- 17 + 78427 = 78444
- 43 + 78401 = 78444
- 97 + 78347 = 78444
- 103 + 78341 = 78444
- 127 + 78317 = 78444
- 137 + 78307 = 78444
Showing the first eight; more decompositions exist.
