Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70042, here are decompositions:

3 + 70039 = 70042
23 + 70019 = 70042
41 + 70001 = 70042
83 + 69959 = 70042
101 + 69941 = 70042
113 + 69929 = 70042
131 + 69911 = 70042
233 + 69809 = 70042

Showing the first eight; more decompositions exist.
