Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589174, here are decompositions:

7 + 31589167 = 31589174
37 + 31589137 = 31589174
157 + 31589017 = 31589174
163 + 31589011 = 31589174
181 + 31588993 = 31589174
223 + 31588951 = 31589174
241 + 31588933 = 31589174
277 + 31588897 = 31589174

Showing the first eight; more decompositions exist.
