Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515148, here are decompositions:

5 + 515143 = 515148
37 + 515111 = 515148
59 + 515089 = 515148
61 + 515087 = 515148
107 + 515041 = 515148
181 + 514967 = 515148
199 + 514949 = 515148
281 + 514867 = 515148

Showing the first eight; more decompositions exist.
