Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590486, here are decompositions:

7 + 31590479 = 31590486
17 + 31590469 = 31590486
19 + 31590467 = 31590486
23 + 31590463 = 31590486
43 + 31590443 = 31590486
73 + 31590413 = 31590486
89 + 31590397 = 31590486
173 + 31590313 = 31590486

Showing the first eight; more decompositions exist.
