Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604148, here are decompositions:

11 + 31604137 = 31604148
19 + 31604129 = 31604148
97 + 31604051 = 31604148
157 + 31603991 = 31604148
229 + 31603919 = 31604148
269 + 31603879 = 31604148
271 + 31603877 = 31604148
347 + 31603801 = 31604148

Showing the first eight; more decompositions exist.
