Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40492, here are decompositions:

5 + 40487 = 40492
59 + 40433 = 40492
131 + 40361 = 40492
149 + 40343 = 40492
239 + 40253 = 40492
251 + 40241 = 40492
461 + 40031 = 40492
479 + 40013 = 40492

Showing the first eight; more decompositions exist.
