Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449322, here are decompositions:

59 + 31449263 = 31449322
89 + 31449233 = 31449322
131 + 31449191 = 31449322
239 + 31449083 = 31449322
251 + 31449071 = 31449322
269 + 31449053 = 31449322
293 + 31449029 = 31449322
419 + 31448903 = 31449322

Showing the first eight; more decompositions exist.
