Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 412, here are decompositions:

3 + 409 = 412
11 + 401 = 412
23 + 389 = 412
29 + 383 = 412
53 + 359 = 412
59 + 353 = 412
101 + 311 = 412
131 + 281 = 412

Showing the first eight; more decompositions exist.
