Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023590, here are decompositions:

13 + 1023577 = 1023590
19 + 1023571 = 1023590
103 + 1023487 = 1023590
181 + 1023409 = 1023590
199 + 1023391 = 1023590
223 + 1023367 = 1023590
229 + 1023361 = 1023590
277 + 1023313 = 1023590

Showing the first eight; more decompositions exist.
