Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82722, here are decompositions:
- 23 + 82699 = 82722
- 71 + 82651 = 82722
- 89 + 82633 = 82722
- 103 + 82619 = 82722
- 109 + 82613 = 82722
- 113 + 82609 = 82722
- 131 + 82591 = 82722
- 151 + 82571 = 82722
Showing the first eight; more decompositions exist.
