Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61168, here are decompositions:
- 17 + 61151 = 61168
- 47 + 61121 = 61168
- 137 + 61031 = 61168
- 167 + 61001 = 61168
- 251 + 60917 = 61168
- 269 + 60899 = 61168
- 281 + 60887 = 61168
- 347 + 60821 = 61168
Showing the first eight; more decompositions exist.
