Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009572, here are decompositions:

13 + 1009559 = 1009572
41 + 1009531 = 1009572
71 + 1009501 = 1009572
73 + 1009499 = 1009572
89 + 1009483 = 1009572
139 + 1009433 = 1009572
173 + 1009399 = 1009572
199 + 1009373 = 1009572

Showing the first eight; more decompositions exist.
