Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515740, here are decompositions:

3 + 515737 = 515740
47 + 515693 = 515740
53 + 515687 = 515740
59 + 515681 = 515740
89 + 515651 = 515740
101 + 515639 = 515740
233 + 515507 = 515740
263 + 515477 = 515740

Showing the first eight; more decompositions exist.
