Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604926, here are decompositions:

137 + 31604789 = 31604926
167 + 31604759 = 31604926
179 + 31604747 = 31604926
239 + 31604687 = 31604926
317 + 31604609 = 31604926
569 + 31604357 = 31604926
797 + 31604129 = 31604926
827 + 31604099 = 31604926

Showing the first eight; more decompositions exist.
