Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578378, here are decompositions:

7 + 578371 = 578378
61 + 578317 = 578378
67 + 578311 = 578378
79 + 578299 = 578378
127 + 578251 = 578378
211 + 578167 = 578378
331 + 578047 = 578378
337 + 578041 = 578378

Showing the first eight; more decompositions exist.
