Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972880, here are decompositions:

11 + 972869 = 972880
47 + 972833 = 972880
53 + 972827 = 972880
179 + 972701 = 972880
197 + 972683 = 972880
257 + 972623 = 972880
269 + 972611 = 972880
281 + 972599 = 972880

Showing the first eight; more decompositions exist.
