Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712572, here are decompositions:

151 + 8712421 = 8712572
199 + 8712373 = 8712572
223 + 8712349 = 8712572
313 + 8712259 = 8712572
409 + 8712163 = 8712572
439 + 8712133 = 8712572
601 + 8711971 = 8712572
619 + 8711953 = 8712572

Showing the first eight; more decompositions exist.
