Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751222, here are decompositions:

41 + 8751181 = 8751222
71 + 8751151 = 8751222
79 + 8751143 = 8751222
83 + 8751139 = 8751222
131 + 8751091 = 8751222
281 + 8750941 = 8751222
331 + 8750891 = 8751222
349 + 8750873 = 8751222

Showing the first eight; more decompositions exist.
