Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82830, here are decompositions:
- 17 + 82813 = 82830
- 19 + 82811 = 82830
- 31 + 82799 = 82830
- 37 + 82793 = 82830
- 43 + 82787 = 82830
- 67 + 82763 = 82830
- 71 + 82759 = 82830
- 73 + 82757 = 82830
Showing the first eight; more decompositions exist.
