Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590652, here are decompositions:

3 + 31590649 = 31590652
59 + 31590593 = 31590652
101 + 31590551 = 31590652
173 + 31590479 = 31590652
239 + 31590413 = 31590652
251 + 31590401 = 31590652
281 + 31590371 = 31590652
383 + 31590269 = 31590652

Showing the first eight; more decompositions exist.
