Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604244, here are decompositions:

17 + 31604227 = 31604244
53 + 31604191 = 31604244
107 + 31604137 = 31604244
193 + 31604051 = 31604244
211 + 31604033 = 31604244
257 + 31603987 = 31604244
311 + 31603933 = 31604244
313 + 31603931 = 31604244

Showing the first eight; more decompositions exist.
