Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749164, here are decompositions:

13 + 8749151 = 8749164
23 + 8749141 = 8749164
31 + 8749133 = 8749164
37 + 8749127 = 8749164
43 + 8749121 = 8749164
157 + 8749007 = 8749164
163 + 8749001 = 8749164
173 + 8748991 = 8749164

Showing the first eight; more decompositions exist.
