Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742462, here are decompositions:

13 + 8742449 = 8742462
41 + 8742421 = 8742462
61 + 8742401 = 8742462
83 + 8742379 = 8742462
103 + 8742359 = 8742462
109 + 8742353 = 8742462
149 + 8742313 = 8742462
199 + 8742263 = 8742462

Showing the first eight; more decompositions exist.
