Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003580, here are decompositions:

31 + 1003549 = 1003580
37 + 1003543 = 1003580
73 + 1003507 = 1003580
163 + 1003417 = 1003580
199 + 1003381 = 1003580
211 + 1003369 = 1003580
229 + 1003351 = 1003580
307 + 1003273 = 1003580

Showing the first eight; more decompositions exist.
