Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756406, here are decompositions:

5 + 8756401 = 8756406
13 + 8756393 = 8756406
73 + 8756333 = 8756406
83 + 8756323 = 8756406
89 + 8756317 = 8756406
107 + 8756299 = 8756406
167 + 8756239 = 8756406
173 + 8756233 = 8756406

Showing the first eight; more decompositions exist.
