Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8734978, here are decompositions:

59 + 8734919 = 8734978
137 + 8734841 = 8734978
281 + 8734697 = 8734978
401 + 8734577 = 8734978
467 + 8734511 = 8734978
509 + 8734469 = 8734978
557 + 8734421 = 8734978
617 + 8734361 = 8734978

Showing the first eight; more decompositions exist.
