Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515466, here are decompositions:

37 + 515429 = 515466
89 + 515377 = 515466
97 + 515369 = 515466
109 + 515357 = 515466
173 + 515293 = 515466
229 + 515237 = 515466
233 + 515233 = 515466
239 + 515227 = 515466

Showing the first eight; more decompositions exist.
