Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018300, here are decompositions:

29 + 1018271 = 1018300
47 + 1018253 = 1018300
53 + 1018247 = 1018300
83 + 1018217 = 1018300
191 + 1018109 = 1018300
281 + 1018019 = 1018300
293 + 1018007 = 1018300
347 + 1017953 = 1018300

Showing the first eight; more decompositions exist.
