Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8734780, here are decompositions:

11 + 8734769 = 8734780
23 + 8734757 = 8734780
83 + 8734697 = 8734780
137 + 8734643 = 8734780
167 + 8734613 = 8734780
269 + 8734511 = 8734780
311 + 8734469 = 8734780
359 + 8734421 = 8734780

Showing the first eight; more decompositions exist.
