Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623574, here are decompositions:

151 + 8623423 = 8623574
181 + 8623393 = 8623574
283 + 8623291 = 8623574
313 + 8623261 = 8623574
433 + 8623141 = 8623574
523 + 8623051 = 8623574
541 + 8623033 = 8623574
571 + 8623003 = 8623574

Showing the first eight; more decompositions exist.
