Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103742, here are decompositions:

19 + 103723 = 103742
43 + 103699 = 103742
61 + 103681 = 103742
73 + 103669 = 103742
151 + 103591 = 103742
181 + 103561 = 103742
193 + 103549 = 103742
271 + 103471 = 103742

Showing the first eight; more decompositions exist.
