Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705378, here are decompositions:

67 + 8705311 = 8705378
79 + 8705299 = 8705378
109 + 8705269 = 8705378
211 + 8705167 = 8705378
229 + 8705149 = 8705378
337 + 8705041 = 8705378
349 + 8705029 = 8705378
397 + 8704981 = 8705378

Showing the first eight; more decompositions exist.
