Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622542, here are decompositions:

13 + 8622529 = 8622542
31 + 8622511 = 8622542
43 + 8622499 = 8622542
73 + 8622469 = 8622542
79 + 8622463 = 8622542
151 + 8622391 = 8622542
163 + 8622379 = 8622542
199 + 8622343 = 8622542

Showing the first eight; more decompositions exist.
