Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103844, here are decompositions:

3 + 103841 = 103844
7 + 103837 = 103844
31 + 103813 = 103844
43 + 103801 = 103844
157 + 103687 = 103844
163 + 103681 = 103844
193 + 103651 = 103844
271 + 103573 = 103844

Showing the first eight; more decompositions exist.
