Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82818, here are decompositions:
- 5 + 82813 = 82818
- 7 + 82811 = 82818
- 19 + 82799 = 82818
- 31 + 82787 = 82818
- 37 + 82781 = 82818
- 59 + 82759 = 82818
- 61 + 82757 = 82818
- 89 + 82729 = 82818
Showing the first eight; more decompositions exist.
