Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56438, here are decompositions:

7 + 56431 = 56438
37 + 56401 = 56438
61 + 56377 = 56438
79 + 56359 = 56438
127 + 56311 = 56438
139 + 56299 = 56438
199 + 56239 = 56438
229 + 56209 = 56438

Showing the first eight; more decompositions exist.
