Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718572, here are decompositions:

103 + 8718469 = 8718572
223 + 8718349 = 8718572
229 + 8718343 = 8718572
271 + 8718301 = 8718572
409 + 8718163 = 8718572
463 + 8718109 = 8718572
613 + 8717959 = 8718572
691 + 8717881 = 8718572

Showing the first eight; more decompositions exist.
