Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61940, here are decompositions:
- 7 + 61933 = 61940
- 13 + 61927 = 61940
- 31 + 61909 = 61940
- 61 + 61879 = 61940
- 79 + 61861 = 61940
- 97 + 61843 = 61940
- 103 + 61837 = 61940
- 127 + 61813 = 61940
Showing the first eight; more decompositions exist.
