Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706220, here are decompositions:

23 + 8706197 = 8706220
71 + 8706149 = 8706220
113 + 8706107 = 8706220
251 + 8705969 = 8706220
317 + 8705903 = 8706220
359 + 8705861 = 8706220
389 + 8705831 = 8706220
443 + 8705777 = 8706220

Showing the first eight; more decompositions exist.
