Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137178, here are decompositions:

31 + 137147 = 137178
47 + 137131 = 137178
59 + 137119 = 137178
61 + 137117 = 137178
89 + 137089 = 137178
101 + 137077 = 137178
149 + 137029 = 137178
179 + 136999 = 137178

Showing the first eight; more decompositions exist.
