Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61128, here are decompositions:

7 + 61121 = 61128
29 + 61099 = 61128
37 + 61091 = 61128
71 + 61057 = 61128
97 + 61031 = 61128
101 + 61027 = 61128
127 + 61001 = 61128
167 + 60961 = 61128

Showing the first eight; more decompositions exist.
