Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706172, here are decompositions:

3 + 8706169 = 8706172
23 + 8706149 = 8706172
71 + 8706101 = 8706172
113 + 8706059 = 8706172
173 + 8705999 = 8706172
269 + 8705903 = 8706172
311 + 8705861 = 8706172
443 + 8705729 = 8706172

Showing the first eight; more decompositions exist.
