Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604952, here are decompositions:

19 + 31604933 = 31604952
89 + 31604863 = 31604952
103 + 31604849 = 31604952
149 + 31604803 = 31604952
163 + 31604789 = 31604952
193 + 31604759 = 31604952
229 + 31604723 = 31604952
233 + 31604719 = 31604952

Showing the first eight; more decompositions exist.
