Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590046, here are decompositions:

179 + 31589867 = 31590046
227 + 31589819 = 31590046
269 + 31589777 = 31590046
353 + 31589693 = 31590046
479 + 31589567 = 31590046
563 + 31589483 = 31590046
743 + 31589303 = 31590046
863 + 31589183 = 31590046

Showing the first eight; more decompositions exist.
