Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18970, here are decompositions:

11 + 18959 = 18970
23 + 18947 = 18970
53 + 18917 = 18970
59 + 18911 = 18970
71 + 18899 = 18970
101 + 18869 = 18970
131 + 18839 = 18970
167 + 18803 = 18970

Showing the first eight; more decompositions exist.
