Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40636, here are decompositions:

53 + 40583 = 40636
59 + 40577 = 40636
107 + 40529 = 40636
137 + 40499 = 40636
149 + 40487 = 40636
293 + 40343 = 40636
347 + 40289 = 40636
353 + 40283 = 40636

Showing the first eight; more decompositions exist.
