Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11902, here are decompositions:
- 5 + 11897 = 11902
- 71 + 11831 = 11902
- 89 + 11813 = 11902
- 101 + 11801 = 11902
- 113 + 11789 = 11902
- 269 + 11633 = 11902
- 281 + 11621 = 11902
- 353 + 11549 = 11902
Showing the first eight; more decompositions exist.
