Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595828, here are decompositions:

97 + 31595731 = 31595828
109 + 31595719 = 31595828
127 + 31595701 = 31595828
157 + 31595671 = 31595828
421 + 31595407 = 31595828
457 + 31595371 = 31595828
577 + 31595251 = 31595828
619 + 31595209 = 31595828

Showing the first eight; more decompositions exist.
