Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187182, here are decompositions:

5 + 187177 = 187182
11 + 187171 = 187182
19 + 187163 = 187182
41 + 187141 = 187182
43 + 187139 = 187182
53 + 187129 = 187182
59 + 187123 = 187182
71 + 187111 = 187182

Showing the first eight; more decompositions exist.
