Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187416, here are decompositions:

7 + 187409 = 187416
23 + 187393 = 187416
29 + 187387 = 187416
37 + 187379 = 187416
43 + 187373 = 187416
67 + 187349 = 187416
79 + 187337 = 187416
113 + 187303 = 187416

Showing the first eight; more decompositions exist.
