Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604740, here are decompositions:

17 + 31604723 = 31604740
53 + 31604687 = 31604740
59 + 31604681 = 31604740
113 + 31604627 = 31604740
131 + 31604609 = 31604740
137 + 31604603 = 31604740
179 + 31604561 = 31604740
239 + 31604501 = 31604740

Showing the first eight; more decompositions exist.
