Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156372, here are decompositions:

11 + 156361 = 156372
19 + 156353 = 156372
43 + 156329 = 156372
53 + 156319 = 156372
103 + 156269 = 156372
113 + 156259 = 156372
131 + 156241 = 156372
233 + 156139 = 156372

Showing the first eight; more decompositions exist.
