Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515140, here are decompositions:

29 + 515111 = 515140
53 + 515087 = 515140
173 + 514967 = 515140
191 + 514949 = 515140
251 + 514889 = 515140
281 + 514859 = 515140
293 + 514847 = 515140
317 + 514823 = 515140

Showing the first eight; more decompositions exist.
