Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713240, here are decompositions:

23 + 8713217 = 8713240
47 + 8713193 = 8713240
59 + 8713181 = 8713240
83 + 8713157 = 8713240
113 + 8713127 = 8713240
131 + 8713109 = 8713240
197 + 8713043 = 8713240
227 + 8713013 = 8713240

Showing the first eight; more decompositions exist.
