Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38870, here are decompositions:
- 3 + 38867 = 38870
- 19 + 38851 = 38870
- 31 + 38839 = 38870
- 37 + 38833 = 38870
- 67 + 38803 = 38870
- 79 + 38791 = 38870
- 103 + 38767 = 38870
- 157 + 38713 = 38870
Showing the first eight; more decompositions exist.
