Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742194, here are decompositions:

7 + 8742187 = 8742194
37 + 8742157 = 8742194
61 + 8742133 = 8742194
73 + 8742121 = 8742194
127 + 8742067 = 8742194
157 + 8742037 = 8742194
211 + 8741983 = 8742194
271 + 8741923 = 8742194

Showing the first eight; more decompositions exist.
