Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147866, here are decompositions:

3 + 147863 = 147866
7 + 147859 = 147866
13 + 147853 = 147866
67 + 147799 = 147866
73 + 147793 = 147866
79 + 147787 = 147866
97 + 147769 = 147866
127 + 147739 = 147866

Showing the first eight; more decompositions exist.
