Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143930, here are decompositions:
- 97 + 143833 = 143930
- 103 + 143827 = 143930
- 109 + 143821 = 143930
- 139 + 143791 = 143930
- 151 + 143779 = 143930
- 211 + 143719 = 143930
- 277 + 143653 = 143930
- 313 + 143617 = 143930
Showing the first eight; more decompositions exist.
