Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78770, here are decompositions:
- 73 + 78697 = 78770
- 79 + 78691 = 78770
- 127 + 78643 = 78770
- 163 + 78607 = 78770
- 193 + 78577 = 78770
- 199 + 78571 = 78770
- 229 + 78541 = 78770
- 283 + 78487 = 78770
Showing the first eight; more decompositions exist.
