Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148870, here are decompositions:
- 3 + 148867 = 148870
- 11 + 148859 = 148870
- 17 + 148853 = 148870
- 41 + 148829 = 148870
- 53 + 148817 = 148870
- 89 + 148781 = 148870
- 107 + 148763 = 148870
- 149 + 148721 = 148870
Showing the first eight; more decompositions exist.
