Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017972, here are decompositions:

13 + 1017959 = 1017972
19 + 1017953 = 1017972
83 + 1017889 = 1017972
113 + 1017859 = 1017972
173 + 1017799 = 1017972
191 + 1017781 = 1017972
223 + 1017749 = 1017972
251 + 1017721 = 1017972

Showing the first eight; more decompositions exist.
