Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79840, here are decompositions:

11 + 79829 = 79840
17 + 79823 = 79840
23 + 79817 = 79840
29 + 79811 = 79840
71 + 79769 = 79840
83 + 79757 = 79840
149 + 79691 = 79840
227 + 79613 = 79840

Showing the first eight; more decompositions exist.
