Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500778, here are decompositions:

37 + 500741 = 500778
59 + 500719 = 500778
79 + 500699 = 500778
101 + 500677 = 500778
107 + 500671 = 500778
149 + 500629 = 500778
191 + 500587 = 500778
199 + 500579 = 500778

Showing the first eight; more decompositions exist.
