Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604574, here are decompositions:

13 + 31604561 = 31604574
17 + 31604557 = 31604574
41 + 31604533 = 31604574
73 + 31604501 = 31604574
191 + 31604383 = 31604574
227 + 31604347 = 31604574
233 + 31604341 = 31604574
263 + 31604311 = 31604574

Showing the first eight; more decompositions exist.
