Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76920, here are decompositions:

7 + 76913 = 76920
13 + 76907 = 76920
37 + 76883 = 76920
47 + 76873 = 76920
73 + 76847 = 76920
83 + 76837 = 76920
89 + 76831 = 76920
101 + 76819 = 76920

Showing the first eight; more decompositions exist.
