Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172784, here are decompositions:

43 + 172741 = 172784
67 + 172717 = 172784
97 + 172687 = 172784
103 + 172681 = 172784
127 + 172657 = 172784
151 + 172633 = 172784
181 + 172603 = 172784
211 + 172573 = 172784

Showing the first eight; more decompositions exist.
