Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742294, here are decompositions:

31 + 8742263 = 8742294
97 + 8742197 = 8742294
101 + 8742193 = 8742294
107 + 8742187 = 8742294
137 + 8742157 = 8742294
173 + 8742121 = 8742294
191 + 8742103 = 8742294
227 + 8742067 = 8742294

Showing the first eight; more decompositions exist.
