Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109442, here are decompositions:

19 + 109423 = 109442
79 + 109363 = 109442
139 + 109303 = 109442
163 + 109279 = 109442
241 + 109201 = 109442
271 + 109171 = 109442
283 + 109159 = 109442
331 + 109111 = 109442

Showing the first eight; more decompositions exist.
