Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589624, here are decompositions:

13 + 31589611 = 31589624
151 + 31589473 = 31589624
163 + 31589461 = 31589624
223 + 31589401 = 31589624
271 + 31589353 = 31589624
307 + 31589317 = 31589624
331 + 31589293 = 31589624
337 + 31589287 = 31589624

Showing the first eight; more decompositions exist.
