Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590074, here are decompositions:

3 + 31590071 = 31590074
13 + 31590061 = 31590074
37 + 31590037 = 31590074
67 + 31590007 = 31590074
97 + 31589977 = 31590074
151 + 31589923 = 31590074
337 + 31589737 = 31590074
367 + 31589707 = 31590074

Showing the first eight; more decompositions exist.
