Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725000, here are decompositions:

17 + 8724983 = 8725000
71 + 8724929 = 8725000
173 + 8724827 = 8725000
197 + 8724803 = 8725000
281 + 8724719 = 8725000
359 + 8724641 = 8725000
503 + 8724497 = 8725000
521 + 8724479 = 8725000

Showing the first eight; more decompositions exist.
