Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90178, here are decompositions:

5 + 90173 = 90178
29 + 90149 = 90178
71 + 90107 = 90178
89 + 90089 = 90178
107 + 90071 = 90178
167 + 90011 = 90178
239 + 89939 = 90178
269 + 89909 = 90178

Showing the first eight; more decompositions exist.
