Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613028, here are decompositions:

59 + 8612969 = 8613028
71 + 8612957 = 8613028
101 + 8612927 = 8613028
167 + 8612861 = 8613028
191 + 8612837 = 8613028
197 + 8612831 = 8613028
227 + 8612801 = 8613028
251 + 8612777 = 8613028

Showing the first eight; more decompositions exist.
