Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590674, here are decompositions:

7 + 31590667 = 31590674
43 + 31590631 = 31590674
103 + 31590571 = 31590674
211 + 31590463 = 31590674
223 + 31590451 = 31590674
277 + 31590397 = 31590674
331 + 31590343 = 31590674
397 + 31590277 = 31590674

Showing the first eight; more decompositions exist.
