Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742222, here are decompositions:

29 + 8742193 = 8742222
53 + 8742169 = 8742222
61 + 8742161 = 8742222
89 + 8742133 = 8742222
101 + 8742121 = 8742222
163 + 8742059 = 8742222
211 + 8742011 = 8742222
233 + 8741989 = 8742222

Showing the first eight; more decompositions exist.
