Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101784, here are decompositions:

13 + 101771 = 101784
37 + 101747 = 101784
43 + 101741 = 101784
47 + 101737 = 101784
61 + 101723 = 101784
83 + 101701 = 101784
103 + 101681 = 101784
131 + 101653 = 101784

Showing the first eight; more decompositions exist.
