Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538120, here are decompositions:

3 + 538117 = 538120
41 + 538079 = 538120
47 + 538073 = 538120
71 + 538049 = 538120
101 + 538019 = 538120
179 + 537941 = 538120
347 + 537773 = 538120
509 + 537611 = 538120

Showing the first eight; more decompositions exist.
