Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70890, here are decompositions:

11 + 70879 = 70890
13 + 70877 = 70890
23 + 70867 = 70890
37 + 70853 = 70890
41 + 70849 = 70890
47 + 70843 = 70890
67 + 70823 = 70890
97 + 70793 = 70890

Showing the first eight; more decompositions exist.
