Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61040, here are decompositions:

13 + 61027 = 61040
79 + 60961 = 61040
97 + 60943 = 61040
103 + 60937 = 61040
127 + 60913 = 61040
139 + 60901 = 61040
151 + 60889 = 61040
181 + 60859 = 61040

Showing the first eight; more decompositions exist.
