Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611212, here are decompositions:

11 + 8611201 = 8611212
31 + 8611181 = 8611212
61 + 8611151 = 8611212
73 + 8611139 = 8611212
79 + 8611133 = 8611212
149 + 8611063 = 8611212
179 + 8611033 = 8611212
251 + 8610961 = 8611212

Showing the first eight; more decompositions exist.
