Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79112, here are decompositions:
- 73 + 79039 = 79112
- 193 + 78919 = 79112
- 211 + 78901 = 79112
- 223 + 78889 = 79112
- 331 + 78781 = 79112
- 421 + 78691 = 79112
- 463 + 78649 = 79112
- 541 + 78571 = 79112
Showing the first eight; more decompositions exist.
