Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012240, here are decompositions:

11 + 1012229 = 1012240
23 + 1012217 = 1012240
107 + 1012133 = 1012240
137 + 1012103 = 1012240
191 + 1012049 = 1012240
197 + 1012043 = 1012240
233 + 1012007 = 1012240
293 + 1011947 = 1012240

Showing the first eight; more decompositions exist.
