Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2436, here are decompositions:

13 + 2423 = 2436
19 + 2417 = 2436
37 + 2399 = 2436
43 + 2393 = 2436
47 + 2389 = 2436
53 + 2383 = 2436
59 + 2377 = 2436
79 + 2357 = 2436

Showing the first eight; more decompositions exist.
