Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620942, here are decompositions:

101 + 8620841 = 8620942
251 + 8620691 = 8620942
269 + 8620673 = 8620942
311 + 8620631 = 8620942
353 + 8620589 = 8620942
389 + 8620553 = 8620942
443 + 8620499 = 8620942
593 + 8620349 = 8620942

Showing the first eight; more decompositions exist.
