Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673538, here are decompositions:

149 + 8673389 = 8673538
179 + 8673359 = 8673538
191 + 8673347 = 8673538
197 + 8673341 = 8673538
317 + 8673221 = 8673538
431 + 8673107 = 8673538
509 + 8673029 = 8673538
569 + 8672969 = 8673538

Showing the first eight; more decompositions exist.
