Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508378, here are decompositions:

5 + 508373 = 508378
11 + 508367 = 508378
29 + 508349 = 508378
47 + 508331 = 508378
107 + 508271 = 508378
149 + 508229 = 508378
191 + 508187 = 508378
281 + 508097 = 508378

Showing the first eight; more decompositions exist.
