Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972278, here are decompositions:

7 + 972271 = 972278
19 + 972259 = 972278
79 + 972199 = 972278
157 + 972121 = 972278
199 + 972079 = 972278
277 + 972001 = 972278
379 + 971899 = 972278
421 + 971857 = 972278

Showing the first eight; more decompositions exist.
