Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146820, here are decompositions:

13 + 146807 = 146820
19 + 146801 = 146820
43 + 146777 = 146820
53 + 146767 = 146820
71 + 146749 = 146820
101 + 146719 = 146820
137 + 146683 = 146820
139 + 146681 = 146820

Showing the first eight; more decompositions exist.
