Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103442, here are decompositions:

19 + 103423 = 103442
43 + 103399 = 103442
109 + 103333 = 103442
151 + 103291 = 103442
211 + 103231 = 103442
271 + 103171 = 103442
349 + 103093 = 103442
373 + 103069 = 103442

Showing the first eight; more decompositions exist.
