Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504322, here are decompositions:

19 + 31504303 = 31504322
103 + 31504219 = 31504322
139 + 31504183 = 31504322
193 + 31504129 = 31504322
271 + 31504051 = 31504322
349 + 31503973 = 31504322
439 + 31503883 = 31504322
523 + 31503799 = 31504322

Showing the first eight; more decompositions exist.
