Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559582, here are decompositions:

139 + 31559443 = 31559582
181 + 31559401 = 31559582
199 + 31559383 = 31559582
211 + 31559371 = 31559582
331 + 31559251 = 31559582
421 + 31559161 = 31559582
433 + 31559149 = 31559582
619 + 31558963 = 31559582

Showing the first eight; more decompositions exist.
