Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78518, here are decompositions:
- 7 + 78511 = 78518
- 31 + 78487 = 78518
- 79 + 78439 = 78518
- 151 + 78367 = 78518
- 211 + 78307 = 78518
- 241 + 78277 = 78518
- 277 + 78241 = 78518
- 379 + 78139 = 78518
Showing the first eight; more decompositions exist.
