Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559432, here are decompositions:

19 + 31559413 = 31559432
31 + 31559401 = 31559432
61 + 31559371 = 31559432
181 + 31559251 = 31559432
193 + 31559239 = 31559432
271 + 31559161 = 31559432
283 + 31559149 = 31559432
439 + 31558993 = 31559432

Showing the first eight; more decompositions exist.
