Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661994, here are decompositions:

17 + 8661977 = 8661994
41 + 8661953 = 8661994
53 + 8661941 = 8661994
113 + 8661881 = 8661994
227 + 8661767 = 8661994
251 + 8661743 = 8661994
311 + 8661683 = 8661994
353 + 8661641 = 8661994

Showing the first eight; more decompositions exist.
