Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690160, here are decompositions:

41 + 8690119 = 8690160
43 + 8690117 = 8690160
67 + 8690093 = 8690160
71 + 8690089 = 8690160
97 + 8690063 = 8690160
163 + 8689997 = 8690160
173 + 8689987 = 8690160
179 + 8689981 = 8690160

Showing the first eight; more decompositions exist.
