Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589330, here are decompositions:

13 + 31589317 = 31589330
37 + 31589293 = 31589330
43 + 31589287 = 31589330
79 + 31589251 = 31589330
163 + 31589167 = 31589330
193 + 31589137 = 31589330
211 + 31589119 = 31589330
313 + 31589017 = 31589330

Showing the first eight; more decompositions exist.
