Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77440, here are decompositions:
- 23 + 77417 = 77440
- 71 + 77369 = 77440
- 89 + 77351 = 77440
- 101 + 77339 = 77440
- 149 + 77291 = 77440
- 173 + 77267 = 77440
- 179 + 77261 = 77440
- 191 + 77249 = 77440
Showing the first eight; more decompositions exist.
