Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654442, here are decompositions:

11 + 8654431 = 8654442
53 + 8654389 = 8654442
61 + 8654381 = 8654442
103 + 8654339 = 8654442
109 + 8654333 = 8654442
193 + 8654249 = 8654442
211 + 8654231 = 8654442
241 + 8654201 = 8654442

Showing the first eight; more decompositions exist.
