Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658018, here are decompositions:

137 + 8657881 = 8658018
167 + 8657851 = 8658018
191 + 8657827 = 8658018
251 + 8657767 = 8658018
331 + 8657687 = 8658018
337 + 8657681 = 8658018
367 + 8657651 = 8658018
379 + 8657639 = 8658018

Showing the first eight; more decompositions exist.
