Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559336, here are decompositions:

19 + 31559317 = 31559336
73 + 31559263 = 31559336
97 + 31559239 = 31559336
373 + 31558963 = 31559336
379 + 31558957 = 31559336
397 + 31558939 = 31559336
409 + 31558927 = 31559336
439 + 31558897 = 31559336

Showing the first eight; more decompositions exist.
