Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687090, here are decompositions:

3 + 8687087 = 8687090
109 + 8686981 = 8687090
283 + 8686807 = 8687090
421 + 8686669 = 8687090
439 + 8686651 = 8687090
523 + 8686567 = 8687090
619 + 8686471 = 8687090
631 + 8686459 = 8687090

Showing the first eight; more decompositions exist.
