Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756180, here are decompositions:

31 + 8756149 = 8756180
61 + 8756119 = 8756180
67 + 8756113 = 8756180
73 + 8756107 = 8756180
79 + 8756101 = 8756180
229 + 8755951 = 8756180
331 + 8755849 = 8756180
439 + 8755741 = 8756180

Showing the first eight; more decompositions exist.
