Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562896, here are decompositions:

47 + 31562849 = 31562896
269 + 31562627 = 31562896
293 + 31562603 = 31562896
353 + 31562543 = 31562896
467 + 31562429 = 31562896
653 + 31562243 = 31562896
683 + 31562213 = 31562896
797 + 31562099 = 31562896

Showing the first eight; more decompositions exist.
