Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10830, here are decompositions:

31 + 10799 = 10830
41 + 10789 = 10830
59 + 10771 = 10830
97 + 10733 = 10830
101 + 10729 = 10830
107 + 10723 = 10830
139 + 10691 = 10830
163 + 10667 = 10830

Showing the first eight; more decompositions exist.
