Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 452, here are decompositions:

3 + 449 = 452
13 + 439 = 452
19 + 433 = 452
31 + 421 = 452
43 + 409 = 452
73 + 379 = 452
79 + 373 = 452
103 + 349 = 452

Showing the first eight; more decompositions exist.
