Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742518, here are decompositions:

7 + 8742511 = 8742518
19 + 8742499 = 8742518
97 + 8742421 = 8742518
139 + 8742379 = 8742518
151 + 8742367 = 8742518
331 + 8742187 = 8742518
349 + 8742169 = 8742518
397 + 8742121 = 8742518

Showing the first eight; more decompositions exist.
