Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713640, here are decompositions:

37 + 8713603 = 8713640
73 + 8713567 = 8713640
109 + 8713531 = 8713640
127 + 8713513 = 8713640
181 + 8713459 = 8713640
193 + 8713447 = 8713640
211 + 8713429 = 8713640
241 + 8713399 = 8713640

Showing the first eight; more decompositions exist.
