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.
