Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742412, here are decompositions:

11 + 8742401 = 8742412
53 + 8742359 = 8742412
59 + 8742353 = 8742412
149 + 8742263 = 8742412
251 + 8742161 = 8742412
353 + 8742059 = 8742412
401 + 8742011 = 8742412
461 + 8741951 = 8742412

Showing the first eight; more decompositions exist.
