Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70942, here are decompositions:

5 + 70937 = 70942
23 + 70919 = 70942
29 + 70913 = 70942
41 + 70901 = 70942
89 + 70853 = 70942
101 + 70841 = 70942
149 + 70793 = 70942
173 + 70769 = 70942

Showing the first eight; more decompositions exist.
