Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140816, here are decompositions:

3 + 140813 = 140816
19 + 140797 = 140816
37 + 140779 = 140816
43 + 140773 = 140816
127 + 140689 = 140816
139 + 140677 = 140816
157 + 140659 = 140816
199 + 140617 = 140816

Showing the first eight; more decompositions exist.
