Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172626, here are decompositions:

7 + 172619 = 172626
19 + 172607 = 172626
23 + 172603 = 172626
29 + 172597 = 172626
37 + 172589 = 172626
43 + 172583 = 172626
53 + 172573 = 172626
73 + 172553 = 172626

Showing the first eight; more decompositions exist.
