Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70990, here are decompositions:

11 + 70979 = 70990
41 + 70949 = 70990
53 + 70937 = 70990
71 + 70919 = 70990
89 + 70901 = 70990
113 + 70877 = 70990
137 + 70853 = 70990
149 + 70841 = 70990

Showing the first eight; more decompositions exist.
