Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589210, here are decompositions:

13 + 31589197 = 31589210
43 + 31589167 = 31589210
73 + 31589137 = 31589210
193 + 31589017 = 31589210
199 + 31589011 = 31589210
277 + 31588933 = 31589210
283 + 31588927 = 31589210
313 + 31588897 = 31589210

Showing the first eight; more decompositions exist.
