Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589894, here are decompositions:

3 + 31589891 = 31589894
67 + 31589827 = 31589894
157 + 31589737 = 31589894
163 + 31589731 = 31589894
211 + 31589683 = 31589894
283 + 31589611 = 31589894
421 + 31589473 = 31589894
433 + 31589461 = 31589894

Showing the first eight; more decompositions exist.
