Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642762, here are decompositions:

181 + 8642581 = 8642762
229 + 8642533 = 8642762
313 + 8642449 = 8642762
379 + 8642383 = 8642762
433 + 8642329 = 8642762
643 + 8642119 = 8642762
853 + 8641909 = 8642762
1021 + 8641741 = 8642762

Showing the first eight; more decompositions exist.
