Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61830, here are decompositions:

11 + 61819 = 61830
17 + 61813 = 61830
73 + 61757 = 61830
79 + 61751 = 61830
101 + 61729 = 61830
107 + 61723 = 61830
113 + 61717 = 61830
127 + 61703 = 61830

Showing the first eight; more decompositions exist.
