Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972812, here are decompositions:

13 + 972799 = 972812
19 + 972793 = 972812
151 + 972661 = 972812
163 + 972649 = 972812
199 + 972613 = 972812
331 + 972481 = 972812
409 + 972403 = 972812
439 + 972373 = 972812

Showing the first eight; more decompositions exist.
