Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61956, here are decompositions:
- 7 + 61949 = 61956
- 23 + 61933 = 61956
- 29 + 61927 = 61956
- 47 + 61909 = 61956
- 113 + 61843 = 61956
- 137 + 61819 = 61956
- 199 + 61757 = 61956
- 227 + 61729 = 61956
Showing the first eight; more decompositions exist.
