Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70866, here are decompositions:

13 + 70853 = 70866
17 + 70849 = 70866
23 + 70843 = 70866
43 + 70823 = 70866
73 + 70793 = 70866
83 + 70783 = 70866
97 + 70769 = 70866
113 + 70753 = 70866

Showing the first eight; more decompositions exist.
