Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018236, here are decompositions:

13 + 1018223 = 1018236
19 + 1018217 = 1018236
29 + 1018207 = 1018236
59 + 1018177 = 1018236
113 + 1018123 = 1018236
127 + 1018109 = 1018236
139 + 1018097 = 1018236
179 + 1018057 = 1018236

Showing the first eight; more decompositions exist.
