Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700572, here are decompositions:

43 + 8700529 = 8700572
61 + 8700511 = 8700572
151 + 8700421 = 8700572
211 + 8700361 = 8700572
379 + 8700193 = 8700572
541 + 8700031 = 8700572
571 + 8700001 = 8700572
613 + 8699959 = 8700572

Showing the first eight; more decompositions exist.
