Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172648, here are decompositions:

5 + 172643 = 172648
29 + 172619 = 172648
41 + 172607 = 172648
59 + 172589 = 172648
107 + 172541 = 172648
131 + 172517 = 172648
227 + 172421 = 172648
317 + 172331 = 172648

Showing the first eight; more decompositions exist.
