Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617844, here are decompositions:

7 + 8617837 = 8617844
163 + 8617681 = 8617844
283 + 8617561 = 8617844
331 + 8617513 = 8617844
397 + 8617447 = 8617844
463 + 8617381 = 8617844
607 + 8617237 = 8617844
643 + 8617201 = 8617844

Showing the first eight; more decompositions exist.
