Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61970, here are decompositions:
- 3 + 61967 = 61970
- 37 + 61933 = 61970
- 43 + 61927 = 61970
- 61 + 61909 = 61970
- 109 + 61861 = 61970
- 127 + 61843 = 61970
- 151 + 61819 = 61970
- 157 + 61813 = 61970
Showing the first eight; more decompositions exist.
