Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70256, here are decompositions:

7 + 70249 = 70256
19 + 70237 = 70256
73 + 70183 = 70256
79 + 70177 = 70256
139 + 70117 = 70256
157 + 70099 = 70256
379 + 69877 = 70256
397 + 69859 = 70256

Showing the first eight; more decompositions exist.
