Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749766, here are decompositions:

13 + 8749753 = 8749766
97 + 8749669 = 8749766
139 + 8749627 = 8749766
163 + 8749603 = 8749766
349 + 8749417 = 8749766
409 + 8749357 = 8749766
457 + 8749309 = 8749766
523 + 8749243 = 8749766

Showing the first eight; more decompositions exist.
