Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668250, here are decompositions:

43 + 8668207 = 8668250
109 + 8668141 = 8668250
139 + 8668111 = 8668250
193 + 8668057 = 8668250
271 + 8667979 = 8668250
277 + 8667973 = 8668250
337 + 8667913 = 8668250
379 + 8667871 = 8668250

Showing the first eight; more decompositions exist.
