Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001250, here are decompositions:

13 + 1001237 = 1001250
31 + 1001219 = 1001250
53 + 1001197 = 1001250
59 + 1001191 = 1001250
73 + 1001177 = 1001250
97 + 1001153 = 1001250
127 + 1001123 = 1001250
157 + 1001093 = 1001250

Showing the first eight; more decompositions exist.
