Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478388, here are decompositions:

37 + 478351 = 478388
67 + 478321 = 478388
181 + 478207 = 478388
199 + 478189 = 478388
277 + 478111 = 478388
349 + 478039 = 478388
397 + 477991 = 478388
541 + 477847 = 478388

Showing the first eight; more decompositions exist.
