Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595954, here are decompositions:

73 + 31595881 = 31595954
223 + 31595731 = 31595954
283 + 31595671 = 31595954
373 + 31595581 = 31595954
487 + 31595467 = 31595954
547 + 31595407 = 31595954
571 + 31595383 = 31595954
853 + 31595101 = 31595954

Showing the first eight; more decompositions exist.
