Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184572, here are decompositions:

5 + 184567 = 184572
13 + 184559 = 184572
19 + 184553 = 184572
61 + 184511 = 184572
83 + 184489 = 184572
109 + 184463 = 184572
131 + 184441 = 184572
163 + 184409 = 184572

Showing the first eight; more decompositions exist.
