Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742844, here are decompositions:

23 + 8742821 = 8742844
167 + 8742677 = 8742844
191 + 8742653 = 8742844
293 + 8742551 = 8742844
347 + 8742497 = 8742844
443 + 8742401 = 8742844
491 + 8742353 = 8742844
647 + 8742197 = 8742844

Showing the first eight; more decompositions exist.
