Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61018, here are decompositions:
- 11 + 61007 = 61018
- 17 + 61001 = 61018
- 101 + 60917 = 61018
- 131 + 60887 = 61018
- 149 + 60869 = 61018
- 197 + 60821 = 61018
- 239 + 60779 = 61018
- 257 + 60761 = 61018
Showing the first eight; more decompositions exist.
