Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670154, here are decompositions:

47 + 8670107 = 8670154
83 + 8670071 = 8670154
113 + 8670041 = 8670154
173 + 8669981 = 8670154
191 + 8669963 = 8670154
257 + 8669897 = 8670154
293 + 8669861 = 8670154
503 + 8669651 = 8670154

Showing the first eight; more decompositions exist.
