Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589882, here are decompositions:

13 + 31589869 = 31589882
109 + 31589773 = 31589882
151 + 31589731 = 31589882
199 + 31589683 = 31589882
223 + 31589659 = 31589882
271 + 31589611 = 31589882
409 + 31589473 = 31589882
421 + 31589461 = 31589882

Showing the first eight; more decompositions exist.
