Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589580, here are decompositions:

13 + 31589567 = 31589580
19 + 31589561 = 31589580
41 + 31589539 = 31589580
67 + 31589513 = 31589580
97 + 31589483 = 31589580
107 + 31589473 = 31589580
157 + 31589423 = 31589580
173 + 31589407 = 31589580

Showing the first eight; more decompositions exist.
