Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78244, here are decompositions:
- 3 + 78241 = 78244
- 11 + 78233 = 78244
- 41 + 78203 = 78244
- 53 + 78191 = 78244
- 71 + 78173 = 78244
- 107 + 78137 = 78244
- 227 + 78017 = 78244
- 293 + 77951 = 78244
Showing the first eight; more decompositions exist.
