Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589510, here are decompositions:

37 + 31589473 = 31589510
103 + 31589407 = 31589510
109 + 31589401 = 31589510
151 + 31589359 = 31589510
157 + 31589353 = 31589510
181 + 31589329 = 31589510
193 + 31589317 = 31589510
223 + 31589287 = 31589510

Showing the first eight; more decompositions exist.
