Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642024, here are decompositions:

37 + 8641987 = 8642024
67 + 8641957 = 8642024
151 + 8641873 = 8642024
241 + 8641783 = 8642024
277 + 8641747 = 8642024
283 + 8641741 = 8642024
373 + 8641651 = 8642024
421 + 8641603 = 8642024

Showing the first eight; more decompositions exist.
