Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749628, here are decompositions:

79 + 8749549 = 8749628
211 + 8749417 = 8749628
271 + 8749357 = 8749628
409 + 8749219 = 8749628
421 + 8749207 = 8749628
487 + 8749141 = 8749628
541 + 8749087 = 8749628
739 + 8748889 = 8749628

Showing the first eight; more decompositions exist.
