Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742778, here are decompositions:

89 + 8742689 = 8742778
101 + 8742677 = 8742778
227 + 8742551 = 8742778
281 + 8742497 = 8742778
419 + 8742359 = 8742778
431 + 8742347 = 8742778
461 + 8742317 = 8742778
617 + 8742161 = 8742778

Showing the first eight; more decompositions exist.
