Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70280, here are decompositions:

31 + 70249 = 70280
43 + 70237 = 70280
73 + 70207 = 70280
79 + 70201 = 70280
97 + 70183 = 70280
103 + 70177 = 70280
139 + 70141 = 70280
157 + 70123 = 70280

Showing the first eight; more decompositions exist.
