Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931580, here are decompositions:

3 + 931577 = 931580
7 + 931573 = 931580
37 + 931543 = 931580
43 + 931537 = 931580
163 + 931417 = 931580
193 + 931387 = 931580
229 + 931351 = 931580
271 + 931309 = 931580

Showing the first eight; more decompositions exist.
