Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691518, here are decompositions:

37 + 8691481 = 8691518
67 + 8691451 = 8691518
127 + 8691391 = 8691518
151 + 8691367 = 8691518
271 + 8691247 = 8691518
307 + 8691211 = 8691518
331 + 8691187 = 8691518
499 + 8691019 = 8691518

Showing the first eight; more decompositions exist.
