Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931430, here are decompositions:

13 + 931417 = 931430
43 + 931387 = 931430
67 + 931363 = 931430
79 + 931351 = 931430
127 + 931303 = 931430
163 + 931267 = 931430
193 + 931237 = 931430
277 + 931153 = 931430

Showing the first eight; more decompositions exist.
