Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742560, here are decompositions:

19 + 8742541 = 8742560
31 + 8742529 = 8742560
61 + 8742499 = 8742560
67 + 8742493 = 8742560
97 + 8742463 = 8742560
139 + 8742421 = 8742560
181 + 8742379 = 8742560
193 + 8742367 = 8742560

Showing the first eight; more decompositions exist.
