Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931230, here are decompositions:

17 + 931213 = 931230
31 + 931199 = 931230
37 + 931193 = 931230
61 + 931169 = 931230
67 + 931163 = 931230
101 + 931129 = 931230
103 + 931127 = 931230
107 + 931123 = 931230

Showing the first eight; more decompositions exist.
