Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742156, here are decompositions:

23 + 8742133 = 8742156
53 + 8742103 = 8742156
79 + 8742077 = 8742156
89 + 8742067 = 8742156
97 + 8742059 = 8742156
167 + 8741989 = 8742156
173 + 8741983 = 8742156
179 + 8741977 = 8742156

Showing the first eight; more decompositions exist.
