Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040780, here are decompositions:

3 + 1040777 = 1040780
31 + 1040749 = 1040780
109 + 1040671 = 1040780
151 + 1040629 = 1040780
199 + 1040581 = 1040780
277 + 1040503 = 1040780
331 + 1040449 = 1040780
373 + 1040407 = 1040780

Showing the first eight; more decompositions exist.
