Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018572, here are decompositions:

13 + 1018559 = 1018572
29 + 1018543 = 1018572
59 + 1018513 = 1018572
83 + 1018489 = 1018572
101 + 1018471 = 1018572
151 + 1018421 = 1018572
263 + 1018309 = 1018572
271 + 1018301 = 1018572

Showing the first eight; more decompositions exist.
