Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589996, here are decompositions:

13 + 31589983 = 31589996
19 + 31589977 = 31589996
43 + 31589953 = 31589996
73 + 31589923 = 31589996
127 + 31589869 = 31589996
223 + 31589773 = 31589996
313 + 31589683 = 31589996
337 + 31589659 = 31589996

Showing the first eight; more decompositions exist.
