Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589756, here are decompositions:

19 + 31589737 = 31589756
73 + 31589683 = 31589756
97 + 31589659 = 31589756
283 + 31589473 = 31589756
349 + 31589407 = 31589756
379 + 31589377 = 31589756
397 + 31589359 = 31589756
439 + 31589317 = 31589756

Showing the first eight; more decompositions exist.
