Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103072, here are decompositions:

3 + 103069 = 103072
5 + 103067 = 103072
23 + 103049 = 103072
29 + 103043 = 103072
71 + 103001 = 103072
89 + 102983 = 103072
191 + 102881 = 103072
311 + 102761 = 103072

Showing the first eight; more decompositions exist.
