Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972500, here are decompositions:

7 + 972493 = 972500
19 + 972481 = 972500
31 + 972469 = 972500
73 + 972427 = 972500
97 + 972403 = 972500
127 + 972373 = 972500
157 + 972343 = 972500
163 + 972337 = 972500

Showing the first eight; more decompositions exist.
