Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78670, here are decompositions:
- 17 + 78653 = 78670
- 47 + 78623 = 78670
- 101 + 78569 = 78670
- 131 + 78539 = 78670
- 173 + 78497 = 78670
- 191 + 78479 = 78670
- 233 + 78437 = 78670
- 269 + 78401 = 78670
Showing the first eight; more decompositions exist.
