Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159870, here are decompositions:
- 13 + 159857 = 159870
- 17 + 159853 = 159870
- 31 + 159839 = 159870
- 37 + 159833 = 159870
- 59 + 159811 = 159870
- 71 + 159799 = 159870
- 79 + 159791 = 159870
- 83 + 159787 = 159870
Showing the first eight; more decompositions exist.
