Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668946, here are decompositions:

73 + 8668873 = 8668946
109 + 8668837 = 8668946
163 + 8668783 = 8668946
337 + 8668609 = 8668946
397 + 8668549 = 8668946
457 + 8668489 = 8668946
463 + 8668483 = 8668946
487 + 8668459 = 8668946

Showing the first eight; more decompositions exist.
