Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589822, here are decompositions:

3 + 31589819 = 31589822
139 + 31589683 = 31589822
163 + 31589659 = 31589822
211 + 31589611 = 31589822
283 + 31589539 = 31589822
349 + 31589473 = 31589822
421 + 31589401 = 31589822
463 + 31589359 = 31589822

Showing the first eight; more decompositions exist.
