Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11898, here are decompositions:
- 11 + 11887 = 11898
- 31 + 11867 = 11898
- 59 + 11839 = 11898
- 67 + 11831 = 11898
- 71 + 11827 = 11898
- 97 + 11801 = 11898
- 109 + 11789 = 11898
- 167 + 11731 = 11898
Showing the first eight; more decompositions exist.
