Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559486, here are decompositions:

19 + 31559467 = 31559486
43 + 31559443 = 31559486
73 + 31559413 = 31559486
103 + 31559383 = 31559486
223 + 31559263 = 31559486
337 + 31559149 = 31559486
523 + 31558963 = 31559486
547 + 31558939 = 31559486

Showing the first eight; more decompositions exist.
