Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589470, here are decompositions:

47 + 31589423 = 31589470
131 + 31589339 = 31589470
137 + 31589333 = 31589470
149 + 31589321 = 31589470
167 + 31589303 = 31589470
173 + 31589297 = 31589470
179 + 31589291 = 31589470
383 + 31589087 = 31589470

Showing the first eight; more decompositions exist.
