Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690248, here are decompositions:

71 + 8690177 = 8690248
131 + 8690117 = 8690248
179 + 8690069 = 8690248
251 + 8689997 = 8690248
269 + 8689979 = 8690248
431 + 8689817 = 8690248
449 + 8689799 = 8690248
521 + 8689727 = 8690248

Showing the first eight; more decompositions exist.
