Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931972, here are decompositions:

5 + 931967 = 931972
23 + 931949 = 931972
29 + 931943 = 931972
59 + 931913 = 931972
71 + 931901 = 931972
89 + 931883 = 931972
113 + 931859 = 931972
191 + 931781 = 931972

Showing the first eight; more decompositions exist.
