Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78722, here are decompositions:
- 31 + 78691 = 78722
- 73 + 78649 = 78722
- 79 + 78643 = 78722
- 139 + 78583 = 78722
- 151 + 78571 = 78722
- 181 + 78541 = 78722
- 211 + 78511 = 78722
- 283 + 78439 = 78722
Showing the first eight; more decompositions exist.
