Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172670, here are decompositions:

7 + 172663 = 172670
13 + 172657 = 172670
37 + 172633 = 172670
67 + 172603 = 172670
73 + 172597 = 172670
97 + 172573 = 172670
109 + 172561 = 172670
151 + 172519 = 172670

Showing the first eight; more decompositions exist.
