Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023380, here are decompositions:

13 + 1023367 = 1023380
19 + 1023361 = 1023380
67 + 1023313 = 1023380
79 + 1023301 = 1023380
103 + 1023277 = 1023380
151 + 1023229 = 1023380
181 + 1023199 = 1023380
313 + 1023067 = 1023380

Showing the first eight; more decompositions exist.
