Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11802, here are decompositions:
- 13 + 11789 = 11802
- 19 + 11783 = 11802
- 23 + 11779 = 11802
- 59 + 11743 = 11802
- 71 + 11731 = 11802
- 83 + 11719 = 11802
- 101 + 11701 = 11802
- 103 + 11699 = 11802
Showing the first eight; more decompositions exist.
