Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595804, here are decompositions:

73 + 31595731 = 31595804
103 + 31595701 = 31595804
151 + 31595653 = 31595804
193 + 31595611 = 31595804
211 + 31595593 = 31595804
223 + 31595581 = 31595804
337 + 31595467 = 31595804
397 + 31595407 = 31595804

Showing the first eight; more decompositions exist.
