Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84018, here are decompositions:
- 7 + 84011 = 84018
- 31 + 83987 = 84018
- 79 + 83939 = 84018
- 97 + 83921 = 84018
- 107 + 83911 = 84018
- 127 + 83891 = 84018
- 149 + 83869 = 84018
- 227 + 83791 = 84018
Showing the first eight; more decompositions exist.
