Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115572, here are decompositions:

11 + 115561 = 115572
19 + 115553 = 115572
59 + 115513 = 115572
73 + 115499 = 115572
101 + 115471 = 115572
103 + 115469 = 115572
113 + 115459 = 115572
151 + 115421 = 115572

Showing the first eight; more decompositions exist.
