Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61154, here are decompositions:
- 3 + 61151 = 61154
- 13 + 61141 = 61154
- 97 + 61057 = 61154
- 103 + 61051 = 61154
- 127 + 61027 = 61154
- 193 + 60961 = 61154
- 211 + 60943 = 61154
- 241 + 60913 = 61154
Showing the first eight; more decompositions exist.
