Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742824, here are decompositions:

3 + 8742821 = 8742824
7 + 8742817 = 8742824
37 + 8742787 = 8742824
151 + 8742673 = 8742824
283 + 8742541 = 8742824
313 + 8742511 = 8742824
331 + 8742493 = 8742824
457 + 8742367 = 8742824

Showing the first eight; more decompositions exist.
