Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70730, here are decompositions:

13 + 70717 = 70730
43 + 70687 = 70730
67 + 70663 = 70730
73 + 70657 = 70730
103 + 70627 = 70730
109 + 70621 = 70730
157 + 70573 = 70730
181 + 70549 = 70730

Showing the first eight; more decompositions exist.
