Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81926, here are decompositions:
- 7 + 81919 = 81926
- 43 + 81883 = 81926
- 73 + 81853 = 81926
- 79 + 81847 = 81926
- 109 + 81817 = 81926
- 127 + 81799 = 81926
- 157 + 81769 = 81926
- 199 + 81727 = 81926
Showing the first eight; more decompositions exist.
