Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938130, here are decompositions:

13 + 938117 = 938130
23 + 938107 = 938130
31 + 938099 = 938130
41 + 938089 = 938130
47 + 938083 = 938130
59 + 938071 = 938130
71 + 938059 = 938130
73 + 938057 = 938130

Showing the first eight; more decompositions exist.
