Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624744, here are decompositions:

3 + 31624741 = 31624744
5 + 31624739 = 31624744
71 + 31624673 = 31624744
83 + 31624661 = 31624744
101 + 31624643 = 31624744
113 + 31624631 = 31624744
131 + 31624613 = 31624744
197 + 31624547 = 31624744

Showing the first eight; more decompositions exist.
