Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185572, here are decompositions:

3 + 185569 = 185572
5 + 185567 = 185572
29 + 185543 = 185572
41 + 185531 = 185572
53 + 185519 = 185572
89 + 185483 = 185572
131 + 185441 = 185572
263 + 185309 = 185572

Showing the first eight; more decompositions exist.
