Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731572, here are decompositions:

41 + 8731531 = 8731572
43 + 8731529 = 8731572
61 + 8731511 = 8731572
71 + 8731501 = 8731572
79 + 8731493 = 8731572
139 + 8731433 = 8731572
191 + 8731381 = 8731572
229 + 8731343 = 8731572

Showing the first eight; more decompositions exist.
