Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179142, here are decompositions:

23 + 179119 = 179142
31 + 179111 = 179142
43 + 179099 = 179142
53 + 179089 = 179142
59 + 179083 = 179142
101 + 179041 = 179142
109 + 179033 = 179142
113 + 179029 = 179142

Showing the first eight; more decompositions exist.
