Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749562, here are decompositions:

13 + 8749549 = 8749562
139 + 8749423 = 8749562
421 + 8749141 = 8749562
571 + 8748991 = 8749562
673 + 8748889 = 8749562
709 + 8748853 = 8749562
751 + 8748811 = 8749562
823 + 8748739 = 8749562

Showing the first eight; more decompositions exist.
