Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511254, here are decompositions:

11 + 511243 = 511254
17 + 511237 = 511254
31 + 511223 = 511254
41 + 511213 = 511254
43 + 511211 = 511254
53 + 511201 = 511254
61 + 511193 = 511254
83 + 511171 = 511254

Showing the first eight; more decompositions exist.
