Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747822, here are decompositions:

3 + 8747819 = 8747822
19 + 8747803 = 8747822
79 + 8747743 = 8747822
199 + 8747623 = 8747822
283 + 8747539 = 8747822
571 + 8747251 = 8747822
631 + 8747191 = 8747822
739 + 8747083 = 8747822

Showing the first eight; more decompositions exist.
