Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78748, here are decompositions:
- 11 + 78737 = 78748
- 41 + 78707 = 78748
- 179 + 78569 = 78748
- 239 + 78509 = 78748
- 251 + 78497 = 78748
- 269 + 78479 = 78748
- 281 + 78467 = 78748
- 311 + 78437 = 78748
Showing the first eight; more decompositions exist.
