Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79972, here are decompositions:

5 + 79967 = 79972
29 + 79943 = 79972
71 + 79901 = 79972
83 + 79889 = 79972
131 + 79841 = 79972
149 + 79823 = 79972
281 + 79691 = 79972
359 + 79613 = 79972

Showing the first eight; more decompositions exist.
