Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147828, here are decompositions:

17 + 147811 = 147828
29 + 147799 = 147828
41 + 147787 = 147828
59 + 147769 = 147828
67 + 147761 = 147828
89 + 147739 = 147828
101 + 147727 = 147828
139 + 147689 = 147828

Showing the first eight; more decompositions exist.
