Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624752, here are decompositions:

11 + 31624741 = 31624752
13 + 31624739 = 31624752
53 + 31624699 = 31624752
79 + 31624673 = 31624752
109 + 31624643 = 31624752
113 + 31624639 = 31624752
139 + 31624613 = 31624752
193 + 31624559 = 31624752

Showing the first eight; more decompositions exist.
