Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624762, here are decompositions:

23 + 31624739 = 31624762
89 + 31624673 = 31624762
101 + 31624661 = 31624762
131 + 31624631 = 31624762
149 + 31624613 = 31624762
251 + 31624511 = 31624762
419 + 31624343 = 31624762
431 + 31624331 = 31624762

Showing the first eight; more decompositions exist.
