Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172668, here are decompositions:

5 + 172663 = 172668
11 + 172657 = 172668
19 + 172649 = 172668
61 + 172607 = 172668
71 + 172597 = 172668
79 + 172589 = 172668
107 + 172561 = 172668
127 + 172541 = 172668

Showing the first eight; more decompositions exist.
