Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742494, here are decompositions:

31 + 8742463 = 8742494
73 + 8742421 = 8742494
127 + 8742367 = 8742494
181 + 8742313 = 8742494
307 + 8742187 = 8742494
337 + 8742157 = 8742494
373 + 8742121 = 8742494
457 + 8742037 = 8742494

Showing the first eight; more decompositions exist.
