Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743572, here are decompositions:

11 + 8743561 = 8743572
23 + 8743549 = 8743572
41 + 8743531 = 8743572
59 + 8743513 = 8743572
73 + 8743499 = 8743572
83 + 8743489 = 8743572
113 + 8743459 = 8743572
151 + 8743421 = 8743572

Showing the first eight; more decompositions exist.
