Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61178, here are decompositions:
- 37 + 61141 = 61178
- 79 + 61099 = 61178
- 127 + 61051 = 61178
- 151 + 61027 = 61178
- 241 + 60937 = 61178
- 277 + 60901 = 61178
- 367 + 60811 = 61178
- 421 + 60757 = 61178
Showing the first eight; more decompositions exist.
