Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621264, here are decompositions:

163 + 8621101 = 8621264
181 + 8621083 = 8621264
271 + 8620993 = 8621264
313 + 8620951 = 8621264
367 + 8620897 = 8621264
541 + 8620723 = 8621264
577 + 8620687 = 8621264
601 + 8620663 = 8621264

Showing the first eight; more decompositions exist.
