Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972578, here are decompositions:

97 + 972481 = 972578
109 + 972469 = 972578
151 + 972427 = 972578
241 + 972337 = 972578
307 + 972271 = 972578
349 + 972229 = 972578
379 + 972199 = 972578
457 + 972121 = 972578

Showing the first eight; more decompositions exist.
