Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559354, here are decompositions:

3 + 31559351 = 31559354
37 + 31559317 = 31559354
103 + 31559251 = 31559354
193 + 31559161 = 31559354
223 + 31559131 = 31559354
283 + 31559071 = 31559354
397 + 31558957 = 31559354
457 + 31558897 = 31559354

Showing the first eight; more decompositions exist.
