Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745780, here are decompositions:

13 + 8745767 = 8745780
31 + 8745749 = 8745780
37 + 8745743 = 8745780
83 + 8745697 = 8745780
97 + 8745683 = 8745780
101 + 8745679 = 8745780
103 + 8745677 = 8745780
167 + 8745613 = 8745780

Showing the first eight; more decompositions exist.
