Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478580, here are decompositions:

7 + 478573 = 478580
97 + 478483 = 478580
127 + 478453 = 478580
139 + 478441 = 478580
163 + 478417 = 478580
181 + 478399 = 478580
229 + 478351 = 478580
241 + 478339 = 478580

Showing the first eight; more decompositions exist.
