Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147810, here are decompositions:

11 + 147799 = 147810
17 + 147793 = 147810
23 + 147787 = 147810
31 + 147779 = 147810
37 + 147773 = 147810
41 + 147769 = 147810
67 + 147743 = 147810
71 + 147739 = 147810

Showing the first eight; more decompositions exist.
