Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172722, here are decompositions:

5 + 172717 = 172722
13 + 172709 = 172722
41 + 172681 = 172722
59 + 172663 = 172722
73 + 172649 = 172722
79 + 172643 = 172722
89 + 172633 = 172722
103 + 172619 = 172722

Showing the first eight; more decompositions exist.
