Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691078, here are decompositions:

59 + 8691019 = 8691078
107 + 8690971 = 8691078
127 + 8690951 = 8691078
131 + 8690947 = 8691078
157 + 8690921 = 8691078
211 + 8690867 = 8691078
251 + 8690827 = 8691078
257 + 8690821 = 8691078

Showing the first eight; more decompositions exist.
