Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604122, here are decompositions:

23 + 31604099 = 31604122
71 + 31604051 = 31604122
89 + 31604033 = 31604122
131 + 31603991 = 31604122
191 + 31603931 = 31604122
233 + 31603889 = 31604122
293 + 31603829 = 31604122
383 + 31603739 = 31604122

Showing the first eight; more decompositions exist.
