Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589734, here are decompositions:

3 + 31589731 = 31589734
23 + 31589711 = 31589734
41 + 31589693 = 31589734
101 + 31589633 = 31589734
167 + 31589567 = 31589734
173 + 31589561 = 31589734
251 + 31589483 = 31589734
311 + 31589423 = 31589734

Showing the first eight; more decompositions exist.
