Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623542, here are decompositions:

13 + 8623529 = 8623542
19 + 8623523 = 8623542
23 + 8623519 = 8623542
113 + 8623429 = 8623542
149 + 8623393 = 8623542
223 + 8623319 = 8623542
251 + 8623291 = 8623542
281 + 8623261 = 8623542

Showing the first eight; more decompositions exist.
