Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618688, here are decompositions:

5 + 8618683 = 8618688
7 + 8618681 = 8618688
97 + 8618591 = 8618688
107 + 8618581 = 8618688
131 + 8618557 = 8618688
311 + 8618377 = 8618688
349 + 8618339 = 8618688
359 + 8618329 = 8618688

Showing the first eight; more decompositions exist.
