Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981170, here are decompositions:

19 + 981151 = 981170
31 + 981139 = 981170
37 + 981133 = 981170
79 + 981091 = 981170
97 + 981073 = 981170
103 + 981067 = 981170
109 + 981061 = 981170
271 + 980899 = 981170

Showing the first eight; more decompositions exist.
