Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577322, here are decompositions:

31 + 31577291 = 31577322
53 + 31577269 = 31577322
59 + 31577263 = 31577322
61 + 31577261 = 31577322
83 + 31577239 = 31577322
89 + 31577233 = 31577322
113 + 31577209 = 31577322
149 + 31577173 = 31577322

Showing the first eight; more decompositions exist.
