Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103830, here are decompositions:

17 + 103813 = 103830
19 + 103811 = 103830
29 + 103801 = 103830
43 + 103787 = 103830
61 + 103769 = 103830
107 + 103723 = 103830
127 + 103703 = 103830
131 + 103699 = 103830

Showing the first eight; more decompositions exist.
