Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624948, here are decompositions:

41 + 31624907 = 31624948
149 + 31624799 = 31624948
167 + 31624781 = 31624948
317 + 31624631 = 31624948
389 + 31624559 = 31624948
401 + 31624547 = 31624948
491 + 31624457 = 31624948
599 + 31624349 = 31624948

Showing the first eight; more decompositions exist.
