Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589666, here are decompositions:

7 + 31589659 = 31589666
127 + 31589539 = 31589666
193 + 31589473 = 31589666
307 + 31589359 = 31589666
313 + 31589353 = 31589666
337 + 31589329 = 31589666
349 + 31589317 = 31589666
373 + 31589293 = 31589666

Showing the first eight; more decompositions exist.
