Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6478, here are decompositions:

5 + 6473 = 6478
29 + 6449 = 6478
89 + 6389 = 6478
149 + 6329 = 6478
167 + 6311 = 6478
179 + 6299 = 6478
191 + 6287 = 6478
257 + 6221 = 6478

Showing the first eight; more decompositions exist.
