Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624906, here are decompositions:

107 + 31624799 = 31624906
167 + 31624739 = 31624906
233 + 31624673 = 31624906
263 + 31624643 = 31624906
293 + 31624613 = 31624906
347 + 31624559 = 31624906
359 + 31624547 = 31624906
449 + 31624457 = 31624906

Showing the first eight; more decompositions exist.
