Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604372, here are decompositions:

13 + 31604359 = 31604372
31 + 31604341 = 31604372
61 + 31604311 = 31604372
73 + 31604299 = 31604372
109 + 31604263 = 31604372
181 + 31604191 = 31604372
439 + 31603933 = 31604372
571 + 31603801 = 31604372

Showing the first eight; more decompositions exist.
