Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637542, here are decompositions:

19 + 8637523 = 8637542
61 + 8637481 = 8637542
163 + 8637379 = 8637542
223 + 8637319 = 8637542
241 + 8637301 = 8637542
379 + 8637163 = 8637542
409 + 8637133 = 8637542
439 + 8637103 = 8637542

Showing the first eight; more decompositions exist.
