Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589514, here are decompositions:

31 + 31589483 = 31589514
41 + 31589473 = 31589514
53 + 31589461 = 31589514
107 + 31589407 = 31589514
113 + 31589401 = 31589514
137 + 31589377 = 31589514
181 + 31589333 = 31589514
193 + 31589321 = 31589514

Showing the first eight; more decompositions exist.
