Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511242, here are decompositions:

5 + 511237 = 511242
19 + 511223 = 511242
29 + 511213 = 511242
31 + 511211 = 511242
41 + 511201 = 511242
71 + 511171 = 511242
73 + 511169 = 511242
79 + 511163 = 511242

Showing the first eight; more decompositions exist.
