Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972872, here are decompositions:

3 + 972869 = 972872
73 + 972799 = 972872
79 + 972793 = 972872
151 + 972721 = 972872
193 + 972679 = 972872
211 + 972661 = 972872
223 + 972649 = 972872
379 + 972493 = 972872

Showing the first eight; more decompositions exist.
