Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500978, here are decompositions:

31 + 500947 = 500978
67 + 500911 = 500978
97 + 500881 = 500978
139 + 500839 = 500978
307 + 500671 = 500978
349 + 500629 = 500978
547 + 500431 = 500978
661 + 500317 = 500978

Showing the first eight; more decompositions exist.
