Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751212, here are decompositions:

31 + 8751181 = 8751212
61 + 8751151 = 8751212
73 + 8751139 = 8751212
199 + 8751013 = 8751212
271 + 8750941 = 8751212
331 + 8750881 = 8751212
499 + 8750713 = 8751212
523 + 8750689 = 8751212

Showing the first eight; more decompositions exist.
