Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718856, here are decompositions:

5 + 8718851 = 8718856
17 + 8718839 = 8718856
23 + 8718833 = 8718856
53 + 8718803 = 8718856
59 + 8718797 = 8718856
317 + 8718539 = 8718856
353 + 8718503 = 8718856
449 + 8718407 = 8718856

Showing the first eight; more decompositions exist.
