Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604752, here are decompositions:

5 + 31604747 = 31604752
29 + 31604723 = 31604752
71 + 31604681 = 31604752
149 + 31604603 = 31604752
191 + 31604561 = 31604752
251 + 31604501 = 31604752
449 + 31604303 = 31604752
563 + 31604189 = 31604752

Showing the first eight; more decompositions exist.
