Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511236, here are decompositions:

13 + 511223 = 511236
23 + 511213 = 511236
43 + 511193 = 511236
59 + 511177 = 511236
67 + 511169 = 511236
73 + 511163 = 511236
83 + 511153 = 511236
113 + 511123 = 511236

Showing the first eight; more decompositions exist.
