Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172612, here are decompositions:

5 + 172607 = 172612
23 + 172589 = 172612
29 + 172583 = 172612
59 + 172553 = 172612
71 + 172541 = 172612
173 + 172439 = 172612
179 + 172433 = 172612
191 + 172421 = 172612

Showing the first eight; more decompositions exist.
