Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590484, here are decompositions:

5 + 31590479 = 31590484
17 + 31590467 = 31590484
41 + 31590443 = 31590484
71 + 31590413 = 31590484
83 + 31590401 = 31590484
113 + 31590371 = 31590484
131 + 31590353 = 31590484
347 + 31590137 = 31590484

Showing the first eight; more decompositions exist.
