Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559032, here are decompositions:

5 + 31559027 = 31559032
59 + 31558973 = 31559032
149 + 31558883 = 31559032
173 + 31558859 = 31559032
233 + 31558799 = 31559032
359 + 31558673 = 31559032
383 + 31558649 = 31559032
503 + 31558529 = 31559032

Showing the first eight; more decompositions exist.
