Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705370, here are decompositions:

19 + 8705351 = 8705370
59 + 8705311 = 8705370
71 + 8705299 = 8705370
73 + 8705297 = 8705370
101 + 8705269 = 8705370
109 + 8705261 = 8705370
151 + 8705219 = 8705370
199 + 8705171 = 8705370

Showing the first eight; more decompositions exist.
