Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604944, here are decompositions:

11 + 31604933 = 31604944
197 + 31604747 = 31604944
257 + 31604687 = 31604944
263 + 31604681 = 31604944
317 + 31604627 = 31604944
383 + 31604561 = 31604944
443 + 31604501 = 31604944
491 + 31604453 = 31604944

Showing the first eight; more decompositions exist.
