Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512122, here are decompositions:

29 + 512093 = 512122
101 + 512021 = 512122
113 + 512009 = 512122
131 + 511991 = 512122
263 + 511859 = 512122
311 + 511811 = 512122
419 + 511703 = 512122
431 + 511691 = 512122

Showing the first eight; more decompositions exist.
