Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697130, here are decompositions:

3 + 8697127 = 8697130
17 + 8697113 = 8697130
23 + 8697107 = 8697130
41 + 8697089 = 8697130
131 + 8696999 = 8697130
137 + 8696993 = 8697130
179 + 8696951 = 8697130
191 + 8696939 = 8697130

Showing the first eight; more decompositions exist.
