Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604248, here are decompositions:

29 + 31604219 = 31604248
59 + 31604189 = 31604248
149 + 31604099 = 31604248
191 + 31604057 = 31604248
197 + 31604051 = 31604248
257 + 31603991 = 31604248
317 + 31603931 = 31604248
359 + 31603889 = 31604248

Showing the first eight; more decompositions exist.
