Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172764, here are decompositions:

5 + 172759 = 172764
13 + 172751 = 172764
23 + 172741 = 172764
43 + 172721 = 172764
47 + 172717 = 172764
83 + 172681 = 172764
101 + 172663 = 172764
107 + 172657 = 172764

Showing the first eight; more decompositions exist.
