Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589690, here are decompositions:

7 + 31589683 = 31589690
31 + 31589659 = 31589690
79 + 31589611 = 31589690
151 + 31589539 = 31589690
229 + 31589461 = 31589690
283 + 31589407 = 31589690
313 + 31589377 = 31589690
331 + 31589359 = 31589690

Showing the first eight; more decompositions exist.
