Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624614, here are decompositions:

17 + 31624597 = 31624614
23 + 31624591 = 31624614
67 + 31624547 = 31624614
103 + 31624511 = 31624614
107 + 31624507 = 31624614
137 + 31624477 = 31624614
157 + 31624457 = 31624614
191 + 31624423 = 31624614

Showing the first eight; more decompositions exist.
