Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981174, here are decompositions:

23 + 981151 = 981174
37 + 981137 = 981174
41 + 981133 = 981174
83 + 981091 = 981174
97 + 981077 = 981174
101 + 981073 = 981174
107 + 981067 = 981174
113 + 981061 = 981174

Showing the first eight; more decompositions exist.
