Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023542, here are decompositions:

43 + 1023499 = 1023542
151 + 1023391 = 1023542
181 + 1023361 = 1023542
229 + 1023313 = 1023542
241 + 1023301 = 1023542
283 + 1023259 = 1023542
313 + 1023229 = 1023542
379 + 1023163 = 1023542

Showing the first eight; more decompositions exist.
