Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691012, here are decompositions:

41 + 8690971 = 8691012
53 + 8690959 = 8691012
59 + 8690953 = 8691012
61 + 8690951 = 8691012
191 + 8690821 = 8691012
199 + 8690813 = 8691012
223 + 8690789 = 8691012
229 + 8690783 = 8691012

Showing the first eight; more decompositions exist.
