Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511580, here are decompositions:

7 + 511573 = 511580
31 + 511549 = 511580
61 + 511519 = 511580
73 + 511507 = 511580
103 + 511477 = 511580
127 + 511453 = 511580
163 + 511417 = 511580
193 + 511387 = 511580

Showing the first eight; more decompositions exist.
