Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658194, here are decompositions:

151 + 8658043 = 8658194
211 + 8657983 = 8658194
271 + 8657923 = 8658194
313 + 8657881 = 8658194
367 + 8657827 = 8658194
463 + 8657731 = 8658194
631 + 8657563 = 8658194
661 + 8657533 = 8658194

Showing the first eight; more decompositions exist.
