Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632442, here are decompositions:

19 + 8632423 = 8632442
31 + 8632411 = 8632442
43 + 8632399 = 8632442
61 + 8632381 = 8632442
79 + 8632363 = 8632442
109 + 8632333 = 8632442
139 + 8632303 = 8632442
163 + 8632279 = 8632442

Showing the first eight; more decompositions exist.
