Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668772, here are decompositions:

31 + 8668741 = 8668772
61 + 8668711 = 8668772
163 + 8668609 = 8668772
223 + 8668549 = 8668772
271 + 8668501 = 8668772
283 + 8668489 = 8668772
313 + 8668459 = 8668772
349 + 8668423 = 8668772

Showing the first eight; more decompositions exist.
