Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589194, here are decompositions:

11 + 31589183 = 31589194
107 + 31589087 = 31589194
137 + 31589057 = 31589194
167 + 31589027 = 31589194
251 + 31588943 = 31589194
347 + 31588847 = 31589194
521 + 31588673 = 31589194
563 + 31588631 = 31589194

Showing the first eight; more decompositions exist.
