Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660436, here are decompositions:

13 + 8660423 = 8660436
17 + 8660419 = 8660436
23 + 8660413 = 8660436
53 + 8660383 = 8660436
67 + 8660369 = 8660436
97 + 8660339 = 8660436
139 + 8660297 = 8660436
149 + 8660287 = 8660436

Showing the first eight; more decompositions exist.
