Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731850, here are decompositions:

19 + 8731831 = 8731850
31 + 8731819 = 8731850
67 + 8731783 = 8731850
73 + 8731777 = 8731850
139 + 8731711 = 8731850
151 + 8731699 = 8731850
163 + 8731687 = 8731850
223 + 8731627 = 8731850

Showing the first eight; more decompositions exist.
