Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2830, here are decompositions:

11 + 2819 = 2830
29 + 2801 = 2830
41 + 2789 = 2830
53 + 2777 = 2830
89 + 2741 = 2830
101 + 2729 = 2830
131 + 2699 = 2830
137 + 2693 = 2830

Showing the first eight; more decompositions exist.
