Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718862, here are decompositions:

3 + 8718859 = 8718862
11 + 8718851 = 8718862
23 + 8718839 = 8718862
29 + 8718833 = 8718862
59 + 8718803 = 8718862
83 + 8718779 = 8718862
281 + 8718581 = 8718862
359 + 8718503 = 8718862

Showing the first eight; more decompositions exist.
