Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590056, here are decompositions:

19 + 31590037 = 31590056
73 + 31589983 = 31590056
79 + 31589977 = 31590056
103 + 31589953 = 31590056
229 + 31589827 = 31590056
283 + 31589773 = 31590056
349 + 31589707 = 31590056
373 + 31589683 = 31590056

Showing the first eight; more decompositions exist.
