Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749626, here are decompositions:

13 + 8749613 = 8749626
19 + 8749607 = 8749626
23 + 8749603 = 8749626
37 + 8749589 = 8749626
47 + 8749579 = 8749626
157 + 8749469 = 8749626
269 + 8749357 = 8749626
283 + 8749343 = 8749626

Showing the first eight; more decompositions exist.
