Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750556, here are decompositions:

5 + 8750551 = 8750556
7 + 8750549 = 8750556
29 + 8750527 = 8750556
37 + 8750519 = 8750556
47 + 8750509 = 8750556
103 + 8750453 = 8750556
109 + 8750447 = 8750556
127 + 8750429 = 8750556

Showing the first eight; more decompositions exist.
