Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79942, here are decompositions:
- 3 + 79939 = 79942
- 41 + 79901 = 79942
- 53 + 79889 = 79942
- 101 + 79841 = 79942
- 113 + 79829 = 79942
- 131 + 79811 = 79942
- 173 + 79769 = 79942
- 251 + 79691 = 79942
Showing the first eight; more decompositions exist.
