Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604098, here are decompositions:

41 + 31604057 = 31604098
47 + 31604051 = 31604098
107 + 31603991 = 31604098
167 + 31603931 = 31604098
179 + 31603919 = 31604098
269 + 31603829 = 31604098
347 + 31603751 = 31604098
359 + 31603739 = 31604098

Showing the first eight; more decompositions exist.
