Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725090, here are decompositions:

53 + 8725037 = 8725090
107 + 8724983 = 8725090
263 + 8724827 = 8725090
449 + 8724641 = 8725090
593 + 8724497 = 8725090
653 + 8724437 = 8725090
719 + 8724371 = 8725090
743 + 8724347 = 8725090

Showing the first eight; more decompositions exist.
