Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043620, here are decompositions:

3 + 1043617 = 1043620
23 + 1043597 = 1043620
29 + 1043591 = 1043620
89 + 1043531 = 1043620
107 + 1043513 = 1043620
131 + 1043489 = 1043620
167 + 1043453 = 1043620
251 + 1043369 = 1043620

Showing the first eight; more decompositions exist.
