Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515636, here are decompositions:

73 + 515563 = 515636
97 + 515539 = 515636
313 + 515323 = 515636
409 + 515227 = 515636
463 + 515173 = 515636
487 + 515149 = 515636
547 + 515089 = 515636
733 + 514903 = 515636

Showing the first eight; more decompositions exist.
