Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515542, here are decompositions:

3 + 515539 = 515542
23 + 515519 = 515542
113 + 515429 = 515542
173 + 515369 = 515542
191 + 515351 = 515542
263 + 515279 = 515542
311 + 515231 = 515542
389 + 515153 = 515542

Showing the first eight; more decompositions exist.
