Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756280, here are decompositions:

17 + 8756263 = 8756280
41 + 8756239 = 8756280
47 + 8756233 = 8756280
59 + 8756221 = 8756280
67 + 8756213 = 8756280
79 + 8756201 = 8756280
131 + 8756149 = 8756280
151 + 8756129 = 8756280

Showing the first eight; more decompositions exist.
