Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972518, here are decompositions:

37 + 972481 = 972518
109 + 972409 = 972518
181 + 972337 = 972518
199 + 972319 = 972518
241 + 972277 = 972518
397 + 972121 = 972518
439 + 972079 = 972518
487 + 972031 = 972518

Showing the first eight; more decompositions exist.
