Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103120, here are decompositions:

29 + 103091 = 103120
41 + 103079 = 103120
53 + 103067 = 103120
71 + 103049 = 103120
113 + 103007 = 103120
137 + 102983 = 103120
167 + 102953 = 103120
191 + 102929 = 103120

Showing the first eight; more decompositions exist.
