Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61100, here are decompositions:

43 + 61057 = 61100
73 + 61027 = 61100
139 + 60961 = 61100
157 + 60943 = 61100
163 + 60937 = 61100
181 + 60919 = 61100
199 + 60901 = 61100
211 + 60889 = 61100

Showing the first eight; more decompositions exist.
