Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61018, here are decompositions:

11 + 61007 = 61018
17 + 61001 = 61018
101 + 60917 = 61018
131 + 60887 = 61018
149 + 60869 = 61018
197 + 60821 = 61018
239 + 60779 = 61018
257 + 60761 = 61018

Showing the first eight; more decompositions exist.
