Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515454, here are decompositions:

53 + 515401 = 515454
73 + 515381 = 515454
83 + 515371 = 515454
97 + 515357 = 515454
103 + 515351 = 515454
131 + 515323 = 515454
223 + 515231 = 515454
227 + 515227 = 515454

Showing the first eight; more decompositions exist.
