Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12572, here are decompositions:

3 + 12569 = 12572
19 + 12553 = 12572
31 + 12541 = 12572
61 + 12511 = 12572
139 + 12433 = 12572
151 + 12421 = 12572
163 + 12409 = 12572
181 + 12391 = 12572

Showing the first eight; more decompositions exist.
