Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742454, here are decompositions:

5 + 8742449 = 8742454
53 + 8742401 = 8742454
101 + 8742353 = 8742454
107 + 8742347 = 8742454
137 + 8742317 = 8742454
191 + 8742263 = 8742454
257 + 8742197 = 8742454
293 + 8742161 = 8742454

Showing the first eight; more decompositions exist.
