Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612216, here are decompositions:

7 + 8612209 = 8612216
97 + 8612119 = 8612216
127 + 8612089 = 8612216
157 + 8612059 = 8612216
229 + 8611987 = 8612216
313 + 8611903 = 8612216
337 + 8611879 = 8612216
367 + 8611849 = 8612216

Showing the first eight; more decompositions exist.
