Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103572, here are decompositions:

5 + 103567 = 103572
11 + 103561 = 103572
19 + 103553 = 103572
23 + 103549 = 103572
43 + 103529 = 103572
61 + 103511 = 103572
89 + 103483 = 103572
101 + 103471 = 103572

Showing the first eight; more decompositions exist.
