Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731006, here are decompositions:

23 + 8730983 = 8731006
29 + 8730977 = 8731006
59 + 8730947 = 8731006
113 + 8730893 = 8731006
149 + 8730857 = 8731006
269 + 8730737 = 8731006
653 + 8730353 = 8731006
719 + 8730287 = 8731006

Showing the first eight; more decompositions exist.
