Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656494, here are decompositions:

13 + 8656481 = 8656494
17 + 8656477 = 8656494
31 + 8656463 = 8656494
61 + 8656433 = 8656494
71 + 8656423 = 8656494
83 + 8656411 = 8656494
101 + 8656393 = 8656494
127 + 8656367 = 8656494

Showing the first eight; more decompositions exist.
