Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70830, here are decompositions:

7 + 70823 = 70830
37 + 70793 = 70830
47 + 70783 = 70830
61 + 70769 = 70830
101 + 70729 = 70830
113 + 70717 = 70830
163 + 70667 = 70830
167 + 70663 = 70830

Showing the first eight; more decompositions exist.
