Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40486, here are decompositions:

3 + 40483 = 40486
53 + 40433 = 40486
59 + 40427 = 40486
197 + 40289 = 40486
233 + 40253 = 40486
293 + 40193 = 40486
317 + 40169 = 40486
359 + 40127 = 40486

Showing the first eight; more decompositions exist.
