Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61216, here are decompositions:
- 5 + 61211 = 61216
- 47 + 61169 = 61216
- 173 + 61043 = 61216
- 263 + 60953 = 61216
- 293 + 60923 = 61216
- 317 + 60899 = 61216
- 347 + 60869 = 61216
- 443 + 60773 = 61216
Showing the first eight; more decompositions exist.
