Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103812, here are decompositions:

11 + 103801 = 103812
43 + 103769 = 103812
89 + 103723 = 103812
109 + 103703 = 103812
113 + 103699 = 103812
131 + 103681 = 103812
193 + 103619 = 103812
199 + 103613 = 103812

Showing the first eight; more decompositions exist.
