Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612220, here are decompositions:

11 + 8612209 = 8612220
53 + 8612167 = 8612220
101 + 8612119 = 8612220
131 + 8612089 = 8612220
163 + 8612057 = 8612220
181 + 8612039 = 8612220
229 + 8611991 = 8612220
233 + 8611987 = 8612220

Showing the first eight; more decompositions exist.
