Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515376, here are decompositions:

5 + 515371 = 515376
7 + 515369 = 515376
19 + 515357 = 515376
53 + 515323 = 515376
83 + 515293 = 515376
97 + 515279 = 515376
139 + 515237 = 515376
149 + 515227 = 515376

Showing the first eight; more decompositions exist.
