Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589826, here are decompositions:

7 + 31589819 = 31589826
53 + 31589773 = 31589826
67 + 31589759 = 31589826
89 + 31589737 = 31589826
167 + 31589659 = 31589826
193 + 31589633 = 31589826
313 + 31589513 = 31589826
353 + 31589473 = 31589826

Showing the first eight; more decompositions exist.
