Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118870, here are decompositions:
- 71 + 118799 = 118870
- 83 + 118787 = 118870
- 113 + 118757 = 118870
- 131 + 118739 = 118870
- 179 + 118691 = 118870
- 197 + 118673 = 118870
- 251 + 118619 = 118870
- 281 + 118589 = 118870
Showing the first eight; more decompositions exist.
