Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103864, here are decompositions:

23 + 103841 = 103864
53 + 103811 = 103864
251 + 103613 = 103864
281 + 103583 = 103864
311 + 103553 = 103864
353 + 103511 = 103864
443 + 103421 = 103864
557 + 103307 = 103864

Showing the first eight; more decompositions exist.
