Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611222, here are decompositions:

3 + 8611219 = 8611222
41 + 8611181 = 8611222
71 + 8611151 = 8611222
83 + 8611139 = 8611222
89 + 8611133 = 8611222
359 + 8610863 = 8611222
419 + 8610803 = 8611222
491 + 8610731 = 8611222

Showing the first eight; more decompositions exist.
