Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 416, here are decompositions:

7 + 409 = 416
19 + 397 = 416
37 + 379 = 416
43 + 373 = 416
67 + 349 = 416
79 + 337 = 416
103 + 313 = 416
109 + 307 = 416

Showing the first eight; more decompositions exist.
