Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761512, here are decompositions:

5 + 8761507 = 8761512
43 + 8761469 = 8761512
59 + 8761453 = 8761512
73 + 8761439 = 8761512
79 + 8761433 = 8761512
83 + 8761429 = 8761512
173 + 8761339 = 8761512
223 + 8761289 = 8761512

Showing the first eight; more decompositions exist.
