Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549532, here are decompositions:

151 + 31549381 = 31549532
193 + 31549339 = 31549532
331 + 31549201 = 31549532
349 + 31549183 = 31549532
433 + 31549099 = 31549532
523 + 31549009 = 31549532
571 + 31548961 = 31549532
661 + 31548871 = 31549532

Showing the first eight; more decompositions exist.
