Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11870, here are decompositions:
- 3 + 11867 = 11870
- 7 + 11863 = 11870
- 31 + 11839 = 11870
- 37 + 11833 = 11870
- 43 + 11827 = 11870
- 127 + 11743 = 11870
- 139 + 11731 = 11870
- 151 + 11719 = 11870
Showing the first eight; more decompositions exist.
