Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109742, here are decompositions:

79 + 109663 = 109742
103 + 109639 = 109742
163 + 109579 = 109742
223 + 109519 = 109742
271 + 109471 = 109742
379 + 109363 = 109742
421 + 109321 = 109742
439 + 109303 = 109742

Showing the first eight; more decompositions exist.
