Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185742, here are decompositions:

5 + 185737 = 185742
19 + 185723 = 185742
31 + 185711 = 185742
43 + 185699 = 185742
59 + 185683 = 185742
61 + 185681 = 185742
101 + 185641 = 185742
149 + 185593 = 185742

Showing the first eight; more decompositions exist.
