Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78778, here are decompositions:
- 41 + 78737 = 78778
- 71 + 78707 = 78778
- 239 + 78539 = 78778
- 269 + 78509 = 78778
- 281 + 78497 = 78778
- 311 + 78467 = 78778
- 431 + 78347 = 78778
- 461 + 78317 = 78778
Showing the first eight; more decompositions exist.
