Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168772, here are decompositions:

3 + 168769 = 168772
11 + 168761 = 168772
29 + 168743 = 168772
41 + 168731 = 168772
53 + 168719 = 168772
59 + 168713 = 168772
173 + 168599 = 168772
239 + 168533 = 168772

Showing the first eight; more decompositions exist.
