Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612964, here are decompositions:

5 + 8612959 = 8612964
7 + 8612957 = 8612964
23 + 8612941 = 8612964
37 + 8612927 = 8612964
71 + 8612893 = 8612964
103 + 8612861 = 8612964
127 + 8612837 = 8612964
163 + 8612801 = 8612964

Showing the first eight; more decompositions exist.
