Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604182, here are decompositions:

53 + 31604129 = 31604182
83 + 31604099 = 31604182
131 + 31604051 = 31604182
149 + 31604033 = 31604182
191 + 31603991 = 31604182
251 + 31603931 = 31604182
263 + 31603919 = 31604182
293 + 31603889 = 31604182

Showing the first eight; more decompositions exist.
