Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749886, here are decompositions:

73 + 8749813 = 8749886
97 + 8749789 = 8749886
283 + 8749603 = 8749886
307 + 8749579 = 8749886
337 + 8749549 = 8749886
463 + 8749423 = 8749886
577 + 8749309 = 8749886
643 + 8749243 = 8749886

Showing the first eight; more decompositions exist.
