Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1004780, here are decompositions:

19 + 1004761 = 1004780
31 + 1004749 = 1004780
37 + 1004743 = 1004780
43 + 1004737 = 1004780
103 + 1004677 = 1004780
109 + 1004671 = 1004780
181 + 1004599 = 1004780
229 + 1004551 = 1004780

Showing the first eight; more decompositions exist.
