Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481578, here are decompositions:

7 + 481571 = 481578
29 + 481549 = 481578
47 + 481531 = 481578
89 + 481489 = 481578
109 + 481469 = 481578
131 + 481447 = 481578
191 + 481387 = 481578
199 + 481379 = 481578

Showing the first eight; more decompositions exist.
