Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745550, here are decompositions:

3 + 8745547 = 8745550
101 + 8745449 = 8745550
113 + 8745437 = 8745550
131 + 8745419 = 8745550
197 + 8745353 = 8745550
239 + 8745311 = 8745550
251 + 8745299 = 8745550
311 + 8745239 = 8745550

Showing the first eight; more decompositions exist.
