Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742324, here are decompositions:

7 + 8742317 = 8742324
11 + 8742313 = 8742324
61 + 8742263 = 8742324
127 + 8742197 = 8742324
131 + 8742193 = 8742324
137 + 8742187 = 8742324
163 + 8742161 = 8742324
167 + 8742157 = 8742324

Showing the first eight; more decompositions exist.
