Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81614, here are decompositions:
- 3 + 81611 = 81614
- 61 + 81553 = 81614
- 67 + 81547 = 81614
- 97 + 81517 = 81614
- 151 + 81463 = 81614
- 157 + 81457 = 81614
- 193 + 81421 = 81614
- 241 + 81373 = 81614
Showing the first eight; more decompositions exist.
