Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8735972, here are decompositions:

31 + 8735941 = 8735972
151 + 8735821 = 8735972
163 + 8735809 = 8735972
211 + 8735761 = 8735972
229 + 8735743 = 8735972
409 + 8735563 = 8735972
463 + 8735509 = 8735972
523 + 8735449 = 8735972

Showing the first eight; more decompositions exist.
