Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523516, here are decompositions:

5 + 523511 = 523516
23 + 523493 = 523516
29 + 523487 = 523516
53 + 523463 = 523516
83 + 523433 = 523516
89 + 523427 = 523516
113 + 523403 = 523516
167 + 523349 = 523516

Showing the first eight; more decompositions exist.
