Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31730, here are decompositions:

3 + 31727 = 31730
7 + 31723 = 31730
31 + 31699 = 31730
43 + 31687 = 31730
67 + 31663 = 31730
73 + 31657 = 31730
103 + 31627 = 31730
157 + 31573 = 31730

Showing the first eight; more decompositions exist.
