Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589744, here are decompositions:

7 + 31589737 = 31589744
13 + 31589731 = 31589744
37 + 31589707 = 31589744
61 + 31589683 = 31589744
271 + 31589473 = 31589744
283 + 31589461 = 31589744
337 + 31589407 = 31589744
367 + 31589377 = 31589744

Showing the first eight; more decompositions exist.
