Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642402, here are decompositions:

19 + 8642383 = 8642402
73 + 8642329 = 8642402
229 + 8642173 = 8642402
283 + 8642119 = 8642402
619 + 8641783 = 8642402
661 + 8641741 = 8642402
733 + 8641669 = 8642402
751 + 8641651 = 8642402

Showing the first eight; more decompositions exist.
