Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100422, here are decompositions:

5 + 100417 = 100422
11 + 100411 = 100422
19 + 100403 = 100422
29 + 100393 = 100422
31 + 100391 = 100422
43 + 100379 = 100422
59 + 100363 = 100422
61 + 100361 = 100422

Showing the first eight; more decompositions exist.
