Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172676, here are decompositions:

3 + 172673 = 172676
13 + 172663 = 172676
19 + 172657 = 172676
43 + 172633 = 172676
73 + 172603 = 172676
79 + 172597 = 172676
103 + 172573 = 172676
157 + 172519 = 172676

Showing the first eight; more decompositions exist.
