Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172690, here are decompositions:

3 + 172687 = 172690
17 + 172673 = 172690
41 + 172649 = 172690
47 + 172643 = 172690
71 + 172619 = 172690
83 + 172607 = 172690
101 + 172589 = 172690
107 + 172583 = 172690

Showing the first eight; more decompositions exist.
