Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738780, here are decompositions:

13 + 8738767 = 8738780
67 + 8738713 = 8738780
73 + 8738707 = 8738780
109 + 8738671 = 8738780
139 + 8738641 = 8738780
199 + 8738581 = 8738780
241 + 8738539 = 8738780
307 + 8738473 = 8738780

Showing the first eight; more decompositions exist.
