Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525248, here are decompositions:

7 + 525241 = 525248
277 + 524971 = 525248
307 + 524941 = 525248
349 + 524899 = 525248
379 + 524869 = 525248
421 + 524827 = 525248
541 + 524707 = 525248
547 + 524701 = 525248

Showing the first eight; more decompositions exist.
