Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723236, here are decompositions:

23 + 8723213 = 8723236
113 + 8723123 = 8723236
173 + 8723063 = 8723236
359 + 8722877 = 8723236
479 + 8722757 = 8723236
563 + 8722673 = 8723236
593 + 8722643 = 8723236
719 + 8722517 = 8723236

Showing the first eight; more decompositions exist.
