Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506322, here are decompositions:

11 + 31506311 = 31506322
59 + 31506263 = 31506322
149 + 31506173 = 31506322
173 + 31506149 = 31506322
251 + 31506071 = 31506322
293 + 31506029 = 31506322
383 + 31505939 = 31506322
401 + 31505921 = 31506322

Showing the first eight; more decompositions exist.
