Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511624, here are decompositions:

41 + 511583 = 511624
83 + 511541 = 511624
101 + 511523 = 511624
137 + 511487 = 511624
167 + 511457 = 511624
233 + 511391 = 511624
263 + 511361 = 511624
401 + 511223 = 511624

Showing the first eight; more decompositions exist.
