Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1848, here are decompositions:

17 + 1831 = 1848
37 + 1811 = 1848
47 + 1801 = 1848
59 + 1789 = 1848
61 + 1787 = 1848
71 + 1777 = 1848
89 + 1759 = 1848
101 + 1747 = 1848

Showing the first eight; more decompositions exist.
