Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164742, here are decompositions:

13 + 164729 = 164742
41 + 164701 = 164742
59 + 164683 = 164742
79 + 164663 = 164742
89 + 164653 = 164742
173 + 164569 = 164742
211 + 164531 = 164742
229 + 164513 = 164742

Showing the first eight; more decompositions exist.
