Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173816, here are decompositions:

37 + 173779 = 173816
43 + 173773 = 173816
73 + 173743 = 173816
103 + 173713 = 173816
109 + 173707 = 173816
157 + 173659 = 173816
199 + 173617 = 173816
277 + 173539 = 173816

Showing the first eight; more decompositions exist.
