Goldbach decomposition

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.
