Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750138, here are decompositions:

31 + 8750107 = 8750138
37 + 8750101 = 8750138
127 + 8750011 = 8750138
157 + 8749981 = 8750138
211 + 8749927 = 8750138
349 + 8749789 = 8750138
367 + 8749771 = 8750138
487 + 8749651 = 8750138

Showing the first eight; more decompositions exist.
