Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79778, here are decompositions:
- 79 + 79699 = 79778
- 109 + 79669 = 79778
- 151 + 79627 = 79778
- 157 + 79621 = 79778
- 199 + 79579 = 79778
- 229 + 79549 = 79778
- 241 + 79537 = 79778
- 367 + 79411 = 79778
Showing the first eight; more decompositions exist.
