Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525322, here are decompositions:

43 + 31525279 = 31525322
61 + 31525261 = 31525322
79 + 31525243 = 31525322
109 + 31525213 = 31525322
139 + 31525183 = 31525322
331 + 31524991 = 31525322
601 + 31524721 = 31525322
823 + 31524499 = 31525322

Showing the first eight; more decompositions exist.
