Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77800, here are decompositions:

3 + 77797 = 77800
17 + 77783 = 77800
53 + 77747 = 77800
89 + 77711 = 77800
101 + 77699 = 77800
113 + 77687 = 77800
179 + 77621 = 77800
227 + 77573 = 77800

Showing the first eight; more decompositions exist.
