Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617972, here are decompositions:

23 + 8617949 = 8617972
29 + 8617943 = 8617972
101 + 8617871 = 8617972
149 + 8617823 = 8617972
173 + 8617799 = 8617972
269 + 8617703 = 8617972
449 + 8617523 = 8617972
599 + 8617373 = 8617972

Showing the first eight; more decompositions exist.
