Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750628, here are decompositions:

37 + 8750591 = 8750628
79 + 8750549 = 8750628
97 + 8750531 = 8750628
101 + 8750527 = 8750628
109 + 8750519 = 8750628
127 + 8750501 = 8750628
137 + 8750491 = 8750628
149 + 8750479 = 8750628

Showing the first eight; more decompositions exist.
