Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173658, here are decompositions:

7 + 173651 = 173658
11 + 173647 = 173658
29 + 173629 = 173658
41 + 173617 = 173658
59 + 173599 = 173658
97 + 173561 = 173658
109 + 173549 = 173658
127 + 173531 = 173658

Showing the first eight; more decompositions exist.
