Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751842, here are decompositions:

3 + 8751839 = 8751842
13 + 8751829 = 8751842
61 + 8751781 = 8751842
103 + 8751739 = 8751842
109 + 8751733 = 8751842
223 + 8751619 = 8751842
349 + 8751493 = 8751842
373 + 8751469 = 8751842

Showing the first eight; more decompositions exist.
