Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589700, here are decompositions:

7 + 31589693 = 31589700
17 + 31589683 = 31589700
41 + 31589659 = 31589700
67 + 31589633 = 31589700
89 + 31589611 = 31589700
139 + 31589561 = 31589700
227 + 31589473 = 31589700
239 + 31589461 = 31589700

Showing the first eight; more decompositions exist.
