Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661932, here are decompositions:

31 + 8661901 = 8661932
43 + 8661889 = 8661932
61 + 8661871 = 8661932
163 + 8661769 = 8661932
199 + 8661733 = 8661932
229 + 8661703 = 8661932
379 + 8661553 = 8661932
463 + 8661469 = 8661932

Showing the first eight; more decompositions exist.
