Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61994, here are decompositions:
- 3 + 61991 = 61994
- 7 + 61987 = 61994
- 13 + 61981 = 61994
- 61 + 61933 = 61994
- 67 + 61927 = 61994
- 151 + 61843 = 61994
- 157 + 61837 = 61994
- 181 + 61813 = 61994
Showing the first eight; more decompositions exist.
