Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578242, here are decompositions:

29 + 578213 = 578242
59 + 578183 = 578242
149 + 578093 = 578242
179 + 578063 = 578242
263 + 577979 = 578242
311 + 577931 = 578242
443 + 577799 = 578242
461 + 577781 = 578242

Showing the first eight; more decompositions exist.
