Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589726, here are decompositions:

19 + 31589707 = 31589726
43 + 31589683 = 31589726
67 + 31589659 = 31589726
349 + 31589377 = 31589726
367 + 31589359 = 31589726
373 + 31589353 = 31589726
397 + 31589329 = 31589726
409 + 31589317 = 31589726

Showing the first eight; more decompositions exist.
