Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42070, here are decompositions:

47 + 42023 = 42070
53 + 42017 = 42070
71 + 41999 = 42070
89 + 41981 = 42070
101 + 41969 = 42070
113 + 41957 = 42070
167 + 41903 = 42070
173 + 41897 = 42070

Showing the first eight; more decompositions exist.
