Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520448, here are decompositions:

37 + 520411 = 520448
67 + 520381 = 520448
79 + 520369 = 520448
109 + 520339 = 520448
139 + 520309 = 520448
151 + 520297 = 520448
157 + 520291 = 520448
337 + 520111 = 520448

Showing the first eight; more decompositions exist.
