Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589544, here are decompositions:

5 + 31589539 = 31589544
31 + 31589513 = 31589544
61 + 31589483 = 31589544
71 + 31589473 = 31589544
83 + 31589461 = 31589544
137 + 31589407 = 31589544
167 + 31589377 = 31589544
191 + 31589353 = 31589544

Showing the first eight; more decompositions exist.
