Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 532478, here are decompositions:

31 + 532447 = 532478
61 + 532417 = 532478
151 + 532327 = 532478
211 + 532267 = 532478
229 + 532249 = 532478
337 + 532141 = 532478
379 + 532099 = 532478
409 + 532069 = 532478

Showing the first eight; more decompositions exist.
