Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705428, here are decompositions:

29 + 8705399 = 8705428
59 + 8705369 = 8705428
131 + 8705297 = 8705428
167 + 8705261 = 8705428
191 + 8705237 = 8705428
257 + 8705171 = 8705428
269 + 8705159 = 8705428
317 + 8705111 = 8705428

Showing the first eight; more decompositions exist.
