Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604266, here are decompositions:

3 + 31604263 = 31604266
47 + 31604219 = 31604266
137 + 31604129 = 31604266
167 + 31604099 = 31604266
233 + 31604033 = 31604266
347 + 31603919 = 31604266
389 + 31603877 = 31604266
509 + 31603757 = 31604266

Showing the first eight; more decompositions exist.
