Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712850, here are decompositions:

23 + 8712827 = 8712850
71 + 8712779 = 8712850
89 + 8712761 = 8712850
101 + 8712749 = 8712850
137 + 8712713 = 8712850
149 + 8712701 = 8712850
173 + 8712677 = 8712850
239 + 8712611 = 8712850

Showing the first eight; more decompositions exist.
