Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756172, here are decompositions:

13 + 8756159 = 8756172
23 + 8756149 = 8756172
43 + 8756129 = 8756172
53 + 8756119 = 8756172
59 + 8756113 = 8756172
71 + 8756101 = 8756172
83 + 8756089 = 8756172
109 + 8756063 = 8756172

Showing the first eight; more decompositions exist.
