Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 479830, here are decompositions:

17 + 479813 = 479830
47 + 479783 = 479830
53 + 479777 = 479830
59 + 479771 = 479830
191 + 479639 = 479830
269 + 479561 = 479830
317 + 479513 = 479830
389 + 479441 = 479830

Showing the first eight; more decompositions exist.
