Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99018, here are decompositions:
- 5 + 99013 = 99018
- 19 + 98999 = 99018
- 37 + 98981 = 99018
- 71 + 98947 = 99018
- 79 + 98939 = 99018
- 89 + 98929 = 99018
- 107 + 98911 = 99018
- 109 + 98909 = 99018
Showing the first eight; more decompositions exist.
