Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147816, here are decompositions:

5 + 147811 = 147816
17 + 147799 = 147816
23 + 147793 = 147816
29 + 147787 = 147816
37 + 147779 = 147816
43 + 147773 = 147816
47 + 147769 = 147816
73 + 147743 = 147816

Showing the first eight; more decompositions exist.
