Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604452, here are decompositions:

149 + 31604303 = 31604452
233 + 31604219 = 31604452
263 + 31604189 = 31604452
353 + 31604099 = 31604452
401 + 31604051 = 31604452
419 + 31604033 = 31604452
461 + 31603991 = 31604452
521 + 31603931 = 31604452

Showing the first eight; more decompositions exist.
