Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40558, here are decompositions:

29 + 40529 = 40558
59 + 40499 = 40558
71 + 40487 = 40558
131 + 40427 = 40558
197 + 40361 = 40558
269 + 40289 = 40558
281 + 40277 = 40558
317 + 40241 = 40558

Showing the first eight; more decompositions exist.
