Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156444, here are decompositions:

7 + 156437 = 156444
23 + 156421 = 156444
73 + 156371 = 156444
83 + 156361 = 156444
97 + 156347 = 156444
137 + 156307 = 156444
191 + 156253 = 156444
227 + 156217 = 156444

Showing the first eight; more decompositions exist.
