Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617874, here are decompositions:

3 + 8617871 = 8617874
37 + 8617837 = 8617874
193 + 8617681 = 8617874
313 + 8617561 = 8617874
457 + 8617417 = 8617874
541 + 8617333 = 8617874
547 + 8617327 = 8617874
613 + 8617261 = 8617874

Showing the first eight; more decompositions exist.
