Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70142, here are decompositions:

3 + 70139 = 70142
19 + 70123 = 70142
31 + 70111 = 70142
43 + 70099 = 70142
103 + 70039 = 70142
139 + 70003 = 70142
151 + 69991 = 70142
211 + 69931 = 70142

Showing the first eight; more decompositions exist.
