Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670130, here are decompositions:

3 + 8670127 = 8670130
23 + 8670107 = 8670130
41 + 8670089 = 8670130
59 + 8670071 = 8670130
89 + 8670041 = 8670130
101 + 8670029 = 8670130
137 + 8669993 = 8670130
149 + 8669981 = 8670130

Showing the first eight; more decompositions exist.
