Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103144, here are decompositions:

3 + 103141 = 103144
53 + 103091 = 103144
101 + 103043 = 103144
137 + 103007 = 103144
191 + 102953 = 103144
233 + 102911 = 103144
263 + 102881 = 103144
347 + 102797 = 103144

Showing the first eight; more decompositions exist.
