Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612228, here are decompositions:

7 + 8612221 = 8612228
19 + 8612209 = 8612228
61 + 8612167 = 8612228
109 + 8612119 = 8612228
139 + 8612089 = 8612228
241 + 8611987 = 8612228
337 + 8611891 = 8612228
349 + 8611879 = 8612228

Showing the first eight; more decompositions exist.
