Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70272, here are decompositions:

23 + 70249 = 70272
31 + 70241 = 70272
43 + 70229 = 70272
71 + 70201 = 70272
73 + 70199 = 70272
89 + 70183 = 70272
109 + 70163 = 70272
131 + 70141 = 70272

Showing the first eight; more decompositions exist.
