Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690148, here are decompositions:

29 + 8690119 = 8690148
31 + 8690117 = 8690148
59 + 8690089 = 8690148
79 + 8690069 = 8690148
107 + 8690041 = 8690148
151 + 8689997 = 8690148
167 + 8689981 = 8690148
179 + 8689969 = 8690148

Showing the first eight; more decompositions exist.
