Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589630, here are decompositions:

19 + 31589611 = 31589630
157 + 31589473 = 31589630
223 + 31589407 = 31589630
229 + 31589401 = 31589630
271 + 31589359 = 31589630
277 + 31589353 = 31589630
313 + 31589317 = 31589630
337 + 31589293 = 31589630

Showing the first eight; more decompositions exist.
