Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8759780, here are decompositions:

19 + 8759761 = 8759780
31 + 8759749 = 8759780
103 + 8759677 = 8759780
199 + 8759581 = 8759780
223 + 8759557 = 8759780
277 + 8759503 = 8759780
313 + 8759467 = 8759780
373 + 8759407 = 8759780

Showing the first eight; more decompositions exist.
