Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40528, here are decompositions:

29 + 40499 = 40528
41 + 40487 = 40528
101 + 40427 = 40528
167 + 40361 = 40528
239 + 40289 = 40528
251 + 40277 = 40528
359 + 40169 = 40528
401 + 40127 = 40528

Showing the first eight; more decompositions exist.
