Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742546, here are decompositions:

5 + 8742541 = 8742546
17 + 8742529 = 8742546
47 + 8742499 = 8742546
53 + 8742493 = 8742546
83 + 8742463 = 8742546
97 + 8742449 = 8742546
167 + 8742379 = 8742546
179 + 8742367 = 8742546

Showing the first eight; more decompositions exist.
