Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756186, here are decompositions:

37 + 8756149 = 8756186
67 + 8756119 = 8756186
73 + 8756113 = 8756186
79 + 8756107 = 8756186
97 + 8756089 = 8756186
223 + 8755963 = 8756186
337 + 8755849 = 8756186
367 + 8755819 = 8756186

Showing the first eight; more decompositions exist.
