Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118840, here are decompositions:
- 41 + 118799 = 118840
- 53 + 118787 = 118840
- 83 + 118757 = 118840
- 89 + 118751 = 118840
- 101 + 118739 = 118840
- 131 + 118709 = 118840
- 149 + 118691 = 118840
- 167 + 118673 = 118840
Showing the first eight; more decompositions exist.
