Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520526, here are decompositions:

79 + 520447 = 520526
103 + 520423 = 520526
157 + 520369 = 520526
163 + 520363 = 520526
229 + 520297 = 520526
313 + 520213 = 520526
397 + 520129 = 520526
463 + 520063 = 520526

Showing the first eight; more decompositions exist.
