Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604694, here are decompositions:

5 + 31604689 = 31604694
7 + 31604687 = 31604694
13 + 31604681 = 31604694
47 + 31604647 = 31604694
53 + 31604641 = 31604694
67 + 31604627 = 31604694
83 + 31604611 = 31604694
137 + 31604557 = 31604694

Showing the first eight; more decompositions exist.
