Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604854, here are decompositions:

5 + 31604849 = 31604854
107 + 31604747 = 31604854
131 + 31604723 = 31604854
167 + 31604687 = 31604854
173 + 31604681 = 31604854
227 + 31604627 = 31604854
251 + 31604603 = 31604854
293 + 31604561 = 31604854

Showing the first eight; more decompositions exist.
