Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731886, here are decompositions:

13 + 8731873 = 8731886
19 + 8731867 = 8731886
67 + 8731819 = 8731886
103 + 8731783 = 8731886
109 + 8731777 = 8731886
199 + 8731687 = 8731886
277 + 8731609 = 8731886
307 + 8731579 = 8731886

Showing the first eight; more decompositions exist.
