Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82920, here are decompositions:
- 7 + 82913 = 82920
- 17 + 82903 = 82920
- 29 + 82891 = 82920
- 31 + 82889 = 82920
- 37 + 82883 = 82920
- 73 + 82847 = 82920
- 83 + 82837 = 82920
- 107 + 82813 = 82920
Showing the first eight; more decompositions exist.
