Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724572, here are decompositions:

13 + 8724559 = 8724572
61 + 8724511 = 8724572
79 + 8724493 = 8724572
151 + 8724421 = 8724572
271 + 8724301 = 8724572
313 + 8724259 = 8724572
331 + 8724241 = 8724572
349 + 8724223 = 8724572

Showing the first eight; more decompositions exist.
