Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70880, here are decompositions:

3 + 70877 = 70880
13 + 70867 = 70880
31 + 70849 = 70880
37 + 70843 = 70880
97 + 70783 = 70880
127 + 70753 = 70880
151 + 70729 = 70880
163 + 70717 = 70880

Showing the first eight; more decompositions exist.
