Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589274, here are decompositions:

23 + 31589251 = 31589274
107 + 31589167 = 31589274
137 + 31589137 = 31589274
257 + 31589017 = 31589274
263 + 31589011 = 31589274
281 + 31588993 = 31589274
317 + 31588957 = 31589274
331 + 31588943 = 31589274

Showing the first eight; more decompositions exist.
