Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747572, here are decompositions:

11 + 8747561 = 8747572
59 + 8747513 = 8747572
83 + 8747489 = 8747572
89 + 8747483 = 8747572
101 + 8747471 = 8747572
131 + 8747441 = 8747572
149 + 8747423 = 8747572
191 + 8747381 = 8747572

Showing the first eight; more decompositions exist.
