Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82872, here are decompositions:
- 59 + 82813 = 82872
- 61 + 82811 = 82872
- 73 + 82799 = 82872
- 79 + 82793 = 82872
- 109 + 82763 = 82872
- 113 + 82759 = 82872
- 149 + 82723 = 82872
- 151 + 82721 = 82872
Showing the first eight; more decompositions exist.
