Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590826, here are decompositions:

23 + 31590803 = 31590826
89 + 31590737 = 31590826
167 + 31590659 = 31590826
233 + 31590593 = 31590826
269 + 31590557 = 31590826
347 + 31590479 = 31590826
359 + 31590467 = 31590826
383 + 31590443 = 31590826

Showing the first eight; more decompositions exist.
