Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12802, here are decompositions:
- 3 + 12799 = 12802
- 11 + 12791 = 12802
- 59 + 12743 = 12802
- 89 + 12713 = 12802
- 113 + 12689 = 12802
- 131 + 12671 = 12802
- 149 + 12653 = 12802
- 191 + 12611 = 12802
Showing the first eight; more decompositions exist.
