Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612222, here are decompositions:

13 + 8612209 = 8612222
103 + 8612119 = 8612222
163 + 8612059 = 8612222
211 + 8612011 = 8612222
331 + 8611891 = 8612222
349 + 8611873 = 8612222
373 + 8611849 = 8612222
433 + 8611789 = 8612222

Showing the first eight; more decompositions exist.
