Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589606, here are decompositions:

67 + 31589539 = 31589606
199 + 31589407 = 31589606
229 + 31589377 = 31589606
277 + 31589329 = 31589606
313 + 31589293 = 31589606
409 + 31589197 = 31589606
439 + 31589167 = 31589606
487 + 31589119 = 31589606

Showing the first eight; more decompositions exist.
