Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738470, here are decompositions:

23 + 8738447 = 8738470
71 + 8738399 = 8738470
107 + 8738363 = 8738470
131 + 8738339 = 8738470
137 + 8738333 = 8738470
197 + 8738273 = 8738470
239 + 8738231 = 8738470
269 + 8738201 = 8738470

Showing the first eight; more decompositions exist.
