Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157260, here are decompositions:

7 + 157253 = 157260
13 + 157247 = 157260
17 + 157243 = 157260
29 + 157231 = 157260
31 + 157229 = 157260
41 + 157219 = 157260
43 + 157217 = 157260
53 + 157207 = 157260

Showing the first eight; more decompositions exist.
