Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152178, here are decompositions:

31 + 152147 = 152178
67 + 152111 = 152178
97 + 152081 = 152178
101 + 152077 = 152178
137 + 152041 = 152178
139 + 152039 = 152178
149 + 152029 = 152178
151 + 152027 = 152178

Showing the first eight; more decompositions exist.
