Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473322, here are decompositions:

59 + 31473263 = 31473322
71 + 31473251 = 31473322
113 + 31473209 = 31473322
131 + 31473191 = 31473322
149 + 31473173 = 31473322
239 + 31473083 = 31473322
281 + 31473041 = 31473322
359 + 31472963 = 31473322

Showing the first eight; more decompositions exist.
