Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731250, here are decompositions:

19 + 8731231 = 8731250
37 + 8731213 = 8731250
97 + 8731153 = 8731250
109 + 8731141 = 8731250
139 + 8731111 = 8731250
181 + 8731069 = 8731250
211 + 8731039 = 8731250
223 + 8731027 = 8731250

Showing the first eight; more decompositions exist.
