Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705146, here are decompositions:

53 + 8705093 = 8705146
59 + 8705087 = 8705146
89 + 8705057 = 8705146
113 + 8705033 = 8705146
137 + 8705009 = 8705146
167 + 8704979 = 8705146
173 + 8704973 = 8705146
179 + 8704967 = 8705146

Showing the first eight; more decompositions exist.
