Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590536, here are decompositions:

37 + 31590499 = 31590536
67 + 31590469 = 31590536
73 + 31590463 = 31590536
139 + 31590397 = 31590536
193 + 31590343 = 31590536
223 + 31590313 = 31590536
349 + 31590187 = 31590536
499 + 31590037 = 31590536

Showing the first eight; more decompositions exist.
