Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589658, here are decompositions:

47 + 31589611 = 31589658
97 + 31589561 = 31589658
197 + 31589461 = 31589658
251 + 31589407 = 31589658
257 + 31589401 = 31589658
281 + 31589377 = 31589658
337 + 31589321 = 31589658
367 + 31589291 = 31589658

Showing the first eight; more decompositions exist.
