Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750842, here are decompositions:

11 + 8750831 = 8750842
59 + 8750783 = 8750842
71 + 8750771 = 8750842
251 + 8750591 = 8750842
293 + 8750549 = 8750842
311 + 8750531 = 8750842
389 + 8750453 = 8750842
479 + 8750363 = 8750842

Showing the first eight; more decompositions exist.
