Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604344, here are decompositions:

3 + 31604341 = 31604344
41 + 31604303 = 31604344
47 + 31604297 = 31604344
293 + 31604051 = 31604344
311 + 31604033 = 31604344
353 + 31603991 = 31604344
467 + 31603877 = 31604344
587 + 31603757 = 31604344

Showing the first eight; more decompositions exist.
