Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538032, here are decompositions:

3 + 31538029 = 31538032
173 + 31537859 = 31538032
311 + 31537721 = 31538032
401 + 31537631 = 31538032
563 + 31537469 = 31538032
599 + 31537433 = 31538032
641 + 31537391 = 31538032
719 + 31537313 = 31538032

Showing the first eight; more decompositions exist.
