Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512228, here are decompositions:

61 + 512167 = 512228
127 + 512101 = 512228
181 + 512047 = 512228
331 + 511897 = 512228
337 + 511891 = 512228
397 + 511831 = 512228
601 + 511627 = 512228
709 + 511519 = 512228

Showing the first eight; more decompositions exist.
