Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589190, here are decompositions:

7 + 31589183 = 31589190
23 + 31589167 = 31589190
53 + 31589137 = 31589190
71 + 31589119 = 31589190
103 + 31589087 = 31589190
163 + 31589027 = 31589190
173 + 31589017 = 31589190
179 + 31589011 = 31589190

Showing the first eight; more decompositions exist.
