Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61000, here are decompositions:

47 + 60953 = 61000
83 + 60917 = 61000
101 + 60899 = 61000
113 + 60887 = 61000
131 + 60869 = 61000
179 + 60821 = 61000
227 + 60773 = 61000
239 + 60761 = 61000

Showing the first eight; more decompositions exist.
