Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64478, here are decompositions:

79 + 64399 = 64478
97 + 64381 = 64478
151 + 64327 = 64478
199 + 64279 = 64478
241 + 64237 = 64478
307 + 64171 = 64478
397 + 64081 = 64478
571 + 63907 = 64478

Showing the first eight; more decompositions exist.
