Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61164, here are decompositions:
- 11 + 61153 = 61164
- 13 + 61151 = 61164
- 23 + 61141 = 61164
- 43 + 61121 = 61164
- 73 + 61091 = 61164
- 107 + 61057 = 61164
- 113 + 61051 = 61164
- 137 + 61027 = 61164
Showing the first eight; more decompositions exist.
