Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705400, here are decompositions:

17 + 8705383 = 8705400
31 + 8705369 = 8705400
89 + 8705311 = 8705400
101 + 8705299 = 8705400
103 + 8705297 = 8705400
131 + 8705269 = 8705400
139 + 8705261 = 8705400
163 + 8705237 = 8705400

Showing the first eight; more decompositions exist.
