Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519904, here are decompositions:

23 + 519881 = 519904
41 + 519863 = 519904
101 + 519803 = 519904
107 + 519797 = 519904
167 + 519737 = 519904
191 + 519713 = 519904
257 + 519647 = 519904
293 + 519611 = 519904

Showing the first eight; more decompositions exist.
