Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750166, here are decompositions:

43 + 8750123 = 8750166
59 + 8750107 = 8750166
97 + 8750069 = 8750166
127 + 8750039 = 8750166
149 + 8750017 = 8750166
239 + 8749927 = 8750166
263 + 8749903 = 8750166
349 + 8749817 = 8750166

Showing the first eight; more decompositions exist.
