Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617940, here are decompositions:

7 + 8617933 = 8617940
13 + 8617927 = 8617940
103 + 8617837 = 8617940
241 + 8617699 = 8617940
313 + 8617627 = 8617940
379 + 8617561 = 8617940
421 + 8617519 = 8617940
523 + 8617417 = 8617940

Showing the first eight; more decompositions exist.
