Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70978, here are decompositions:

29 + 70949 = 70978
41 + 70937 = 70978
59 + 70919 = 70978
101 + 70877 = 70978
137 + 70841 = 70978
269 + 70709 = 70978
311 + 70667 = 70978
359 + 70619 = 70978

Showing the first eight; more decompositions exist.
