Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624802, here are decompositions:

3 + 31624799 = 31624802
19 + 31624783 = 31624802
61 + 31624741 = 31624802
103 + 31624699 = 31624802
163 + 31624639 = 31624802
211 + 31624591 = 31624802
373 + 31624429 = 31624802
379 + 31624423 = 31624802

Showing the first eight; more decompositions exist.
