Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61138, here are decompositions:

17 + 61121 = 61138
47 + 61091 = 61138
107 + 61031 = 61138
131 + 61007 = 61138
137 + 61001 = 61138
239 + 60899 = 61138
251 + 60887 = 61138
269 + 60869 = 61138

Showing the first eight; more decompositions exist.
