Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670542, here are decompositions:

19 + 8670523 = 8670542
43 + 8670499 = 8670542
61 + 8670481 = 8670542
109 + 8670433 = 8670542
211 + 8670331 = 8670542
229 + 8670313 = 8670542
241 + 8670301 = 8670542
613 + 8669929 = 8670542

Showing the first eight; more decompositions exist.
