Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49000, here are decompositions:

11 + 48989 = 49000
47 + 48953 = 49000
53 + 48947 = 49000
131 + 48869 = 49000
179 + 48821 = 49000
191 + 48809 = 49000
233 + 48767 = 49000
239 + 48761 = 49000

Showing the first eight; more decompositions exist.
