Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604154, here are decompositions:

17 + 31604137 = 31604154
97 + 31604057 = 31604154
103 + 31604051 = 31604154
163 + 31603991 = 31604154
167 + 31603987 = 31604154
223 + 31603931 = 31604154
277 + 31603877 = 31604154
311 + 31603843 = 31604154

Showing the first eight; more decompositions exist.
