Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023620, here are decompositions:

19 + 1023601 = 1023620
43 + 1023577 = 1023620
79 + 1023541 = 1023620
211 + 1023409 = 1023620
229 + 1023391 = 1023620
307 + 1023313 = 1023620
331 + 1023289 = 1023620
421 + 1023199 = 1023620

Showing the first eight; more decompositions exist.
