Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589672, here are decompositions:

13 + 31589659 = 31589672
61 + 31589611 = 31589672
199 + 31589473 = 31589672
211 + 31589461 = 31589672
271 + 31589401 = 31589672
313 + 31589359 = 31589672
379 + 31589293 = 31589672
421 + 31589251 = 31589672

Showing the first eight; more decompositions exist.
