Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668194, here are decompositions:

37 + 8668157 = 8668194
43 + 8668151 = 8668194
53 + 8668141 = 8668194
61 + 8668133 = 8668194
83 + 8668111 = 8668194
113 + 8668081 = 8668194
127 + 8668067 = 8668194
131 + 8668063 = 8668194

Showing the first eight; more decompositions exist.
