Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589762, here are decompositions:

3 + 31589759 = 31589762
31 + 31589731 = 31589762
79 + 31589683 = 31589762
103 + 31589659 = 31589762
151 + 31589611 = 31589762
223 + 31589539 = 31589762
409 + 31589353 = 31589762
433 + 31589329 = 31589762

Showing the first eight; more decompositions exist.
