Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604928, here are decompositions:

79 + 31604849 = 31604928
139 + 31604789 = 31604928
181 + 31604747 = 31604928
197 + 31604731 = 31604928
239 + 31604689 = 31604928
241 + 31604687 = 31604928
281 + 31604647 = 31604928
317 + 31604611 = 31604928

Showing the first eight; more decompositions exist.
