Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178110, here are decompositions:

7 + 178103 = 178110
17 + 178093 = 178110
19 + 178091 = 178110
41 + 178069 = 178110
43 + 178067 = 178110
71 + 178039 = 178110
73 + 178037 = 178110
89 + 178021 = 178110

Showing the first eight; more decompositions exist.
