Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931970, here are decompositions:

3 + 931967 = 931970
37 + 931933 = 931970
97 + 931873 = 931970
181 + 931789 = 931970
223 + 931747 = 931970
241 + 931729 = 931970
313 + 931657 = 931970
331 + 931639 = 931970

Showing the first eight; more decompositions exist.
