Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172680, here are decompositions:

7 + 172673 = 172680
17 + 172663 = 172680
23 + 172657 = 172680
31 + 172649 = 172680
37 + 172643 = 172680
47 + 172633 = 172680
61 + 172619 = 172680
73 + 172607 = 172680

Showing the first eight; more decompositions exist.
