Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749746, here are decompositions:

13 + 8749733 = 8749746
139 + 8749607 = 8749746
157 + 8749589 = 8749746
167 + 8749579 = 8749746
197 + 8749549 = 8749746
277 + 8749469 = 8749746
307 + 8749439 = 8749746
389 + 8749357 = 8749746

Showing the first eight; more decompositions exist.
