Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173640, here are decompositions:

11 + 173629 = 173640
23 + 173617 = 173640
41 + 173599 = 173640
67 + 173573 = 173640
79 + 173561 = 173640
97 + 173543 = 173640
101 + 173539 = 173640
109 + 173531 = 173640

Showing the first eight; more decompositions exist.
