Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648780, here are decompositions:

31 + 8648749 = 8648780
43 + 8648737 = 8648780
79 + 8648701 = 8648780
103 + 8648677 = 8648780
223 + 8648557 = 8648780
229 + 8648551 = 8648780
367 + 8648413 = 8648780
409 + 8648371 = 8648780

Showing the first eight; more decompositions exist.
