Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185142, here are decompositions:

5 + 185137 = 185142
11 + 185131 = 185142
19 + 185123 = 185142
43 + 185099 = 185142
53 + 185089 = 185142
71 + 185071 = 185142
73 + 185069 = 185142
79 + 185063 = 185142

Showing the first eight; more decompositions exist.
