Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636542, here are decompositions:

3 + 8636539 = 8636542
29 + 8636513 = 8636542
281 + 8636261 = 8636542
401 + 8636141 = 8636542
419 + 8636123 = 8636542
449 + 8636093 = 8636542
461 + 8636081 = 8636542
503 + 8636039 = 8636542

Showing the first eight; more decompositions exist.
