Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507322, here are decompositions:

3 + 31507319 = 31507322
79 + 31507243 = 31507322
163 + 31507159 = 31507322
241 + 31507081 = 31507322
313 + 31507009 = 31507322
349 + 31506973 = 31507322
373 + 31506949 = 31507322
499 + 31506823 = 31507322

Showing the first eight; more decompositions exist.
