Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156378, here are decompositions:

7 + 156371 = 156378
17 + 156361 = 156378
31 + 156347 = 156378
59 + 156319 = 156378
71 + 156307 = 156378
109 + 156269 = 156378
137 + 156241 = 156378
149 + 156229 = 156378

Showing the first eight; more decompositions exist.
