Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642834, here are decompositions:

61 + 8642773 = 8642834
73 + 8642761 = 8642834
367 + 8642467 = 8642834
661 + 8642173 = 8642834
727 + 8642107 = 8642834
757 + 8642077 = 8642834
877 + 8641957 = 8642834
1051 + 8641783 = 8642834

Showing the first eight; more decompositions exist.
