Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589686, here are decompositions:

3 + 31589683 = 31589686
53 + 31589633 = 31589686
173 + 31589513 = 31589686
263 + 31589423 = 31589686
347 + 31589339 = 31589686
353 + 31589333 = 31589686
383 + 31589303 = 31589686
389 + 31589297 = 31589686

Showing the first eight; more decompositions exist.
