Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461322, here are decompositions:

29 + 31461293 = 31461322
41 + 31461281 = 31461322
131 + 31461191 = 31461322
149 + 31461173 = 31461322
173 + 31461149 = 31461322
311 + 31461011 = 31461322
443 + 31460879 = 31461322
449 + 31460873 = 31461322

Showing the first eight; more decompositions exist.
