Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589360, here are decompositions:

7 + 31589353 = 31589360
31 + 31589329 = 31589360
43 + 31589317 = 31589360
67 + 31589293 = 31589360
73 + 31589287 = 31589360
109 + 31589251 = 31589360
163 + 31589197 = 31589360
193 + 31589167 = 31589360

Showing the first eight; more decompositions exist.
