Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972530, here are decompositions:

37 + 972493 = 972530
61 + 972469 = 972530
103 + 972427 = 972530
127 + 972403 = 972530
157 + 972373 = 972530
193 + 972337 = 972530
211 + 972319 = 972530
271 + 972259 = 972530

Showing the first eight; more decompositions exist.
