Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104572, here are decompositions:

11 + 104561 = 104572
23 + 104549 = 104572
29 + 104543 = 104572
59 + 104513 = 104572
101 + 104471 = 104572
113 + 104459 = 104572
173 + 104399 = 104572
179 + 104393 = 104572

Showing the first eight; more decompositions exist.
