Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100770, here are decompositions:

23 + 100747 = 100770
29 + 100741 = 100770
37 + 100733 = 100770
67 + 100703 = 100770
71 + 100699 = 100770
97 + 100673 = 100770
101 + 100669 = 100770
149 + 100621 = 100770

Showing the first eight; more decompositions exist.
