Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012280, here are decompositions:

13 + 1012267 = 1012280
19 + 1012261 = 1012280
67 + 1012213 = 1012280
79 + 1012201 = 1012280
97 + 1012183 = 1012280
109 + 1012171 = 1012280
193 + 1012087 = 1012280
271 + 1012009 = 1012280

Showing the first eight; more decompositions exist.
