Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671442, here are decompositions:

61 + 8671381 = 8671442
79 + 8671363 = 8671442
103 + 8671339 = 8671442
151 + 8671291 = 8671442
193 + 8671249 = 8671442
211 + 8671231 = 8671442
223 + 8671219 = 8671442
379 + 8671063 = 8671442

Showing the first eight; more decompositions exist.
