Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61938, here are decompositions:
- 5 + 61933 = 61938
- 11 + 61927 = 61938
- 29 + 61909 = 61938
- 59 + 61879 = 61938
- 67 + 61871 = 61938
- 101 + 61837 = 61938
- 157 + 61781 = 61938
- 181 + 61757 = 61938
Showing the first eight; more decompositions exist.
