Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604318, here are decompositions:

7 + 31604311 = 31604318
19 + 31604299 = 31604318
37 + 31604281 = 31604318
127 + 31604191 = 31604318
181 + 31604137 = 31604318
331 + 31603987 = 31604318
439 + 31603879 = 31604318
601 + 31603717 = 31604318

Showing the first eight; more decompositions exist.
