Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589446, here are decompositions:

23 + 31589423 = 31589446
107 + 31589339 = 31589446
113 + 31589333 = 31589446
149 + 31589297 = 31589446
263 + 31589183 = 31589446
347 + 31589099 = 31589446
359 + 31589087 = 31589446
389 + 31589057 = 31589446

Showing the first eight; more decompositions exist.
