Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661976, here are decompositions:

23 + 8661953 = 8661976
137 + 8661839 = 8661976
233 + 8661743 = 8661976
269 + 8661707 = 8661976
293 + 8661683 = 8661976
347 + 8661629 = 8661976
353 + 8661623 = 8661976
419 + 8661557 = 8661976

Showing the first eight; more decompositions exist.
