Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78454, here are decompositions:
- 17 + 78437 = 78454
- 53 + 78401 = 78454
- 107 + 78347 = 78454
- 113 + 78341 = 78454
- 137 + 78317 = 78454
- 251 + 78203 = 78454
- 263 + 78191 = 78454
- 281 + 78173 = 78454
Showing the first eight; more decompositions exist.
