Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589654, here are decompositions:

43 + 31589611 = 31589654
181 + 31589473 = 31589654
193 + 31589461 = 31589654
277 + 31589377 = 31589654
337 + 31589317 = 31589654
367 + 31589287 = 31589654
457 + 31589197 = 31589654
487 + 31589167 = 31589654

Showing the first eight; more decompositions exist.
