Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78718, here are decompositions:
- 5 + 78713 = 78718
- 11 + 78707 = 78718
- 149 + 78569 = 78718
- 179 + 78539 = 78718
- 239 + 78479 = 78718
- 251 + 78467 = 78718
- 281 + 78437 = 78718
- 317 + 78401 = 78718
Showing the first eight; more decompositions exist.
